There is a lot of wealth and knowledge here about these carbs.
I prefer the wet gauge as I feel it is the most accurate in comparison to the tool you mentioned. Just my opinion.
Keep in mind, these carbs are race carb for the track, if you are trying to tune for drivability then this will go beyond the steps of just following instructions. I have found that you will get very intimate with these carbs in order to tune them for spirt drivability and still have good drivability.
The journey is not short.
