I read ethyl maltrol 10% diluted 2%..huh? I'm lost..what does that mean?
What you have going on is Two Proportions. And the reason is Very Few People Use Ethyl Maltol in a Pure Form as a DIY Sweetener.
What they are Suggesting you use is Pure Ethyl Maltol (EM) which has been Diluted with Something, Usually PG or PGA or Both, to a 10% Solution (9 to 1 Ratio)
Then take the Diluted EM and add it to your Flavored
e-liquid 2% by Volume.
If you
buy EM already Diluted to 10% in a Liquid form, which s Very Common, then you just Add 2% of EM to your Mix. But if you buy Pure EM Crystals, than you should Dilute it in a 9:1 Ratio BEFORE you add it to your Mix to Sweeten it.

BTW - The 2% is just a Reference Starting Point. Taste is Subjective. So for Some People, 2% might be Too Much. For Other, 2% Isn't Enough.
But you have to Start Somewhere. And 2% is as Good as Any.
