Well you are indeed entitled to your opinion and I am not going to argue against it. I for one enjoy the update.
I do, however, have some information/knowledge for you to think about.
For example, you like *.1 volt changes from what I gather. Well I hate to tell you that even if it (or any electronic device for that matter) states it is at 4.2V, I assure you that it is not at 4.2V exactly. A meter will show that is more likely ranging from 4.20V-4.29V. In a perfect world, it would be exactly 4.20V like you would want, but this isn't a perfect world unfortunately. Now granted, the eVic rounds up or down in VV due to it being *.1 increments, so it doesn't show this.
There are so many things that can factor into taste that no one answer is right or wrong. As someone stated, you can have two identical atomizer heads with the same resistances and materials, but taste different at the same Watts or Volts. This is something that is likely to always remain a problem.
Opinions are just that ... opinions. If someone doesn't like your opinion, don't crucify them for it (something everyone should learn at times, myself included).
You like volts. Cool, continue doing what you like to do. No one is telling you "do watts or die". If VV works for you, then use it. Plain and simple.
