Attack Speed Reference

I have tried timing triple swing with fraps and here is what I have gotten:

Test 1 (including time in prone position)
2 (fast) // 1230 milliseconds
3 (normal) // 1350 milliseconds
4 (slow A) // 1470 milliseconds
5 (slow B) // 1560 milliseconds
6 (slower) // 1680 milliseconds

Test 2,3,4 (excluding time in prone position)
41(5->2) 1150-1180-1200-1230
45(6->3) 1200-1280-1280-1320
49(7->4) 1350-1380-1380-1470
52(8->5) 1470-1480-1480-1500-1570
56(9->6) 1480-1500-1590

Test 5 (using 1500 as base)
1110/1140
1230
1320
1410
1500

None of these are exact, but the variation seemed to be too great to make any sense...


I don't see how triple is calculated, if it was 750 (normal atk) + 420 (double) + 660 (triple) = 1830, that is too long. So what does the 660 mean?
