09:30 PM rue_bed: k, what did you do
09:30 PM zhanx: i took readings and weighted them over time in an array
09:31 PM zhanx: the more i saw it the more it moved up
09:31 PM zhanx: so i had array (data 1, data 2, time 1)
09:31 PM zhanx: then a sort on it
09:32 PM zhanx: weight that arrray was data 1 , data 2, time, score, level
09:34 PM rue_bed: dont totally get it
09:34 PM rue_bed: running averages?
09:34 PM zhanx: averages taken at the time
09:34 PM zhanx: say i sample 20ms of data, average it, store, it check it for duplicates
09:37 PM zhanx: the more i get into it, the more i realize I didn't take into account for it
