Agreed the actual time saved isn't much, just like with using scales the cleanup doesn't take that much time, but still imho just makes for a much more enjoyable and effortless mixing session. No matter how you mix, big or small, many or few recipes, then you continually have to weigh/measure out the PG, VG and nic before/after coming to the actual flavoring stage, and it's here this approach makes you cut corners and advance directly towards the flavoring stage and simply top-off the bottle, or weigh/measure the premix and add it, instead of needing fine-tuning 3 ingredients in total "extra". When I mix flavored liquids to my 2 vaping relatives, then I weigh and add the flavors and simply top-off the bottle with the premixed base I have in the fridge in a liter bottle already, and which also is my personal ADV all by itself which I just top-off my 100ml dripper "vape" bottle with, continually also.

It's definitely not precise, agreed, but precision isn't needed imho for this part of the process in my specific circumstances, as I only make recipes with max 6% total flavoring and varying from 2-6% in total, and if I was using e.g. between 2% and 30% flavoring, then I probably wouldn't do it this way I must admit. Well scratch that, I probably would still, as it's still just a small/acceptable deviation from the end-result and still pretty much un-noticable blindly or just extremely mildly and neglible, as it's flavoring that's the important part and not PG/VG/nic ratio/amount in small skews imho.

Just like with VG, then some vendors product is much more watery and thin than others and which also would "skew" the result slightly. Additionally then different nic vendors are often varying in the exact nic content also, and many vendors also add varying amounts of DW to VG-nic(from 3 to 15'ish percent!), which again "skews".

A question......would making a base help with keeping the nicotine base from oxidizing at all??

Not so much. Making a base before hand may oxidize within 3 months stored in plastic at room temperature. BUT if it's properly stored in a glass bottle and kept in a refrigerator then it can last for 6 months or more. That's the key proper packaging and storage. If you make enough to last you 3 months then storing it in plastic at room temperature should be ok. I've had base stored in a 1 ltr glass bottle kept in the refrigerator for up to 8 months stay crystal clear and fresh as the day I made it. This bottle was taken out every time I needed to mix so I would estimate it was removed and placed back into refrigeration every 10 days to 2 weeks until it was used up.

    I plan to start mixing 500ml batches of base and just dump 30ml into 60ml bottle and add my 3% flavoring, shake n vape. At my low level of flavoring I don't think the affect on my 8mg nic level will be worth worrying about?

    I premix the base also.
    To figure nic results, I use E-Juice Me Up> Tools> Nic Combine screen.

    enter the mg of your base 7
    enter 0 mg for the flavor
    Making a 30ml bottle, with 3ml of flavor
    Gives 6.3mg/ml juice

    I vape mostly 7mg unflavored, but when I mix flavored, I just put the flavor in the bottle, then top off with the base....let it steep about a month.

    This is how I figured the nic results

    3% skew is imho unnoticable. The 8mg nic will become 7.76mg and the PG/VG ratio neglible skewed too. If you always just simply use 3% flavoring, or whatever other constant value, then you can also just make up for the difference in the premix so the end-result will become exact, but as said unpercievable imho.

    ...but my point relates to that pretty well, because imho premixed base usage makes for a more effortless mixing session as likewise scales also does in regards to less cleanup afterwards...

    This is exactly why I premix my base and use weight to measure. I keep part of my base in a "ketchup" style squirt bottle. So all I need to have for a mixing session are the flavors and the base and the bottles I'll be using the batch from.
    - Set use bottle on scale, tare
    - Add flavorings taring after each
    - Add base, shake well, done.

    I started with premixing the base because I have problems with my hands, so I didn't want to have to handle 100mg nicotine every time I mixed. It's easier, safer and faster for me to prepare the base in a large pyrex measuring cup, use a cordless mixer with an immersion blender on it to mix thoroughly, and use a funnel to put the base into the "dispensing" bottle(s).

    Here's what I need for mixing (the shell box is where I keep my flavorings, but I need to find something larger):

    It would seem to me that the amount of time saved is dependent on what/how one is mixing, several test batches to several large quantity known mixes. Either way, thankfully time is not a big factor for me.
