I like to follow it all mathematically. Getting the perfect 65:35 mix (it's really 13:7) so that the burn is complete and setting the temp to 160 so that water boils off and sugar dosnt carmilize is perfect. There will be NO water left at all and (mathematically at least) a perfect burn.

I try to use the same brand of sugar and KNO3 every time because I've had to readjust the mix between brands. The difference isn't much but consistency is important with rcandy and I get a little OCD with it.
The powdered sugar works but it will have less fuel value so do the burn test and adjust. Note that the amount of starch could differ even when using the same brand.

Thankfully my two chemicles are just as impure the perfect 35:65 leaves nothing behind except a very slight bit of white (enough that it kinda vaporizes away in a couple of seconds)
You should almost never go past 60:30 or 70:40 unless your trying to really change the fuel (some additives call for less sugar) if you do have to break the 30's and 60's try a different brand of something.
