To be honest with you, drops are a very poor indication and measurement method for refilling the cart. Drop size is all over the place, and you never really know how much residual fluid you are starting with.
I converted my 702 carts over to PTB because I believe it wicks better than the stock poly. When it comes time to refill, I just slowly add drops down the "side" of the cart until I get a little puddling at the top. That can be anywhere between 10 and 15 drops... sometimes more depending on the tip on the juice bottle.
When I get the puddling, I stop... push the cart cup back down... and go to town. I might get the slightest flooding when I first start, but I can usually vape through it. If the puddling is excessive, I can use the bottle to suck that last drop back off, or dab it with the edge of a paper towel.

The 702 carts hold right around 0.5ml... usually around 10 carefully-dripped drops
