It's not for easier calcs. Most flavors are in a base of PG and are considered 100% pg. So if you want for example 90% VG juice and you use for example 20% flavoring by volume, you start with 20% of your juice being PG. You will then never be able to reach 100% or 90% VG juice.

In the same way if you use a VG/PG base of a specific mix, or nic base of a specific PG/VG mix, if either of those are the wrong mix you may not be able to achieve the juice you want. The only way to make sure you have the right ingredient mix is to run it through a recipe calculator.

The op was confused as to why some vendors even offered the nic base in a 50/50 blend. The op was also asking how to get a 60/40 nic base and that was broken down for him at the beginning of the thread.
I really do know some folks that order the 50/50 blends because they diy for just themselves and consider it close enough for their purposes. They know all about the flavorings etc and don't want to be bothered with all of that stuff. LOL
Now if they were vendors that would be a different story. But the op was just confused as to why it was even being offered in the first place.
Hope this explains a little bit about the conversation that was going on.

Yep, that's pretty much it. I do see the use of the calculator to be very important as well. Thanks
