Thing to remember with vaping, taste is subjective and unique to the individual user, the same way people like certain food and others don't. With a VV/VW (VP) [variable volt/variable watt (variable power)], this can be dialed in to what you like and prefer. Charts yes they can help to give a general area to look at, however, it is best to go from lowest setting, and slowly bump up the output an incriment at a time. Also certain juices will require less output than other juices that require higher output.
Example, my fruits I like in the 6-7 watt range, other fruits I am at 9 or 10. My tobacco and RY4 flavors I like at 8 to 9 watts. Creams and desert flavors generally 8-10 watts. Mints and menthols 6 watts.
Start a lowest setting like stated, vape a couple hits, not satisfying, bump up to next incriment, vape a couple hits, doing this until you start to get a burnt taste or throat hit is starting to get harsh for you, once that point is reach back it down one or 2 incriments (especially variable voltage mode)
