Yes. Feel free to check Montenten's spreadsheets. Suji and a few others have done some of the mathing/testing as well over on AH forums to confirm dDex sweet spots as well.
However, I will add in the fact that this was tested with Mandau and 99 Twashtar, both offhanding STR Thokcha. Works for Tarutaru as well. Full Dagger merits, 12 DEX and 12 STR. Didn't believe it at first myself until actually using the spreadsheets to double check the information.
