if we wanna see who needs tweaking and do one char every 3-4 days, that would mean we wouldnt have all the data until 4 months from now (when using 3 days each not 4) and im sure we would wanna work on it sooner than that
(and u kinda need all data before u can start on it)
do 3 characters 2 days each, advertise that your gonna do it with a schedule so pros of those characters know to check the boards in those 2 days and you have it all done in 28 days.
we need all data b4 we can start so we see all matchups, and if we start working on modifying some characters with some data and not all, that will effect the opinions on later characters. we also can not change brawl+ version during the time. if we need to make it faster u could do 4 characters per session for a cool 20 days.
