wouldnt it be better to tag on percentage of red area in the heatmap instead of average speed. im currently doing a script with a lot of -300 speed lines but there are a lot of short strokes so it is still very intense (large red area on the heatmap), but if it is done by just average speed it would qualify as medium.
Also depending how its calculated it might be very difficult to reach an average speed of 350+ as 1 line of 100 would need 5 lines of 400 to get it back to an average of 350
so i would use the heatmap and use a formula more or less like if it is less then 15% red/orange in the heatmap it is slow, 15%-30% red/orange medium above 30% it is fast
