I wouldn't put soo much emphasis on puff count, there's just to many variables. For one not every puff you take is the same. Is the tank completely empty every time you fill and start puff count? And are you sure you fill precisely the same every time? Those may not account for the whole juice discrepancies but could account for some. That along with different puffs can make differences from tank to tank. And as a whole, the older the coil, the less puffs you will get. You seem to average 40 to 50 puffs per ml of juice which seems good . I am using at the moment a coil that's 1 ohm on a kayfun mini 3 (which is not going to eat as much juice as your sub ohm tank) and I average like 35. What juice are you actually vaping? A thicker sweeter juice will shorten the life of coil faster, I have some juices that I can get many many tanks out of compared to some that will destroy coil after one tank.

@vapdivrr im vaping a variety of juices mostly clear and custards, some strawberry banana and a variety of other juices. I heard chocolate flavored juices ruin coils? The darker the juice the rougher it is? What you are saying makes sense!!

So it doesn't sound like your using a juice that really gunk coils too much and should get some good results with your coil in general. Yes net juices (naturally extracted tobaccos ) and darker, kind of thicker sweeter juices can definitely reduce the overall longevity of a coil. more often, people talk about days or weeks, rather then puffs when considering coil longevity, so this is pretty interesting imo. I'm just not sure what your actually curious about, the overall longevity, or why puff count differs from tank to tank? If the later, one would think the puff count should be fairly consistent, but when dealing with such small amounts of liquid , there just seems to be too many variables imo. I know the puff counter happens when you fire the mod but the puff itself can vary soo much itself. I know personally, sometimes I will do a mtl, while sometimes can do a direct lung inhale. Personally I think that is the biggest variable along with the exact filling and draining levels. You seem to have a discrepancy of maybe 1ml of liquid and tbh 1 ml (if you really look at it) is not alot of liquid.

I was just wondering why at first I'd get so many more puffs then after a few tanks really. I'm happy on how long my coils are lasting now 7 plus days.
I must have gotten lucky. I am on week 3 of my first coil in my Crown tank and week 2 of 1st coil in my other. I am using the .5's tho. Havent even tried the .25's yes cause I am loving them so much. I also havent even cleaned either tank/coil yet. Combine that with a new build on my velocity I just discovered and man oh man... I am in Vape heaven right now. The only problem I have is which mod to grab. I try to spread the love so they dont get jealous :vapor:

Just looked and didn't realize the difference between tank 1&2 and Daviedog is probably right because there's probably not alot of gunk that soon. I actually would of thought the second tank would be better because it would be broken in by then. I can see the differences in all the rest of the list, but that first and second is a big difference. Maybe try this test again on your next coil to see if the same discrepancy exists, it would be interesting.

@vapdivrr it maybe due to the fact that I'm priming the coil during the coil taking

It's possible the first tank gets more puffs due to priming the coil? I take numerous small puffs to prime the coil. Here is what I have so far on the same coil. I feel my tanks up to the same level every time also. Puffs are pretty consistent as well.
Tank 1-238 puffs
Tank 2-169 puffs
Tank 3-215 puffs
Tank 4-147 puffs
Tank 5-148 puffs
Tank 6-153 puffs
Tank 7-133 puffs
Tank 8-166 puffs
Tank 9-159 puffs
Tank10-186 puffs

How about efficiency of the batteries? Although a regulated mod, could the batteries have something to do with it? I know sometimes when my batteries are more then 3/4 drained, I feel the vape suffering slightly ? Also connection issues might cause slight variations, if in wattage mode, sometimes the tank may not be making the best connection and the resistance can be read higher and more power is put into the coil to maintain wattage. It is possible little variable like that can make slight differences also

@vapdivrr I'm running samsungs 300mah 3.7v I have two pairs that are married and charge them with a vc2 plus master charger. I do run them until they get low. I haven't really notice a decrease in the amount of puffs. My .25 coil I run 55-60 watts and let's say it's a 60 watts and the batteries are low the joytech adjust the wattage automatically or just draws what the batteries are capable of when low. I'll see the screen drop from 60 to let's say 44 watts or whatever power is available so I don't think it's stressing the coil

Coil gunk impedes efficiency.
If you don't sub-ohm a coil from 28-24AWG will last for a long time, even years.
Simply take off the wick and heat up the coil until it is bright red and dip in a bowl of cold water and the gunk will come off and the coil will be good as new !
I'm pretty sure it's pre built coils.

@EdT586 what do u mean by sub-ohm a coil from 28-24awg? Take off the wick wick means cotton right? So the in store bought coils pre made I can take the cotton out, heat it up till its red then drop in cold water and then what? I'm getting seven days at least out of my coils which I'm happy with was just wondering why the big variations from the first tank to the others. But I think it maybe due to the small puffs i take to prime my coils.

Just a thought for slight variations , these may not add up to much, but maybe a little. I just don't think every time you hit the button, the coil heats up to the exact temperature each and every time. Another can be intervals between puffs. If you take 2 puffs within let's say 5 seconds of each other, you may be using a different amount of juice then if you took one puff then waited a couple minutes. Maybe being the coil is still hot in example 1, the amount of juice used is different. Again unless the test was done in a laboritory on a machine with eveyone variable exactly the same, I think there will be differences in puff count from tank to tank. Personally I think the power of your inhale and time the button is pressed is the number one reason why puff count differs, all other little variables occur also, but just not sure how much they actually differ puff counts. So maybe the question is," what is the number one reason puffs differ from tank to tank" yes overall the coil will not be as efficient because it's slowly getting gunked but that is not the reason if you look at your graph.

Very true @vapdivrr now I don't really care about the amounts of puff per tank I'm just happy my coils are lasting longer :) someone at my
Local vape shop was impressed I was getting ten tanks per coil lol. I've primed the one I'm using now and took my time and just finished my tenth tank and there is no compromise in the taste or quality of puffs I'm getting. Not a dry or burnt hit yet :)

Awesome...... anyways I thought it was an interesting topic, never really thought about exact differences like that.

Yes @vapdivrr store bought pre made coils.

Well if it is pre-made coils you're out of luck, most pre made coils uses 30-32AWG wires that are very very thin and most of those are standard coils which will give off less heat so more gunk will accumulate then compared with a larger gauge micro coil.

Typical standard coil heat up

Not sure you were following the posts close enough, he was talking about a totally different coil

Yeah I knew he was talking about pre-made coils. These RDA coil build samples give larger picture of how they look inside those pre-made cartridges.
