If Nemekh's spreadsheet is correct:

1000 CRIT = 104.95%
1000 DHIT = 104%
1000 DET = 104.2%

1500 CRIT = 107.76%
1500 DHIT = 107.2%
1500 DET = 107.2%

2000 CRIT = 111%
2000 DHIT = 110.35%
2000 DET = 110.2%

So we clearly see: CRIT is the best Stat (even in low tiers). Followed by DHIT and DET which switch their positions at about 1500. Lower DET is better and higher DHIT is better.

Question is: Is that spreadsheet really correct?
