Decided to make an excel sheet to assist the OP in showing this:

Currently its just for mnk/pup, and dual wield. I will add a section later for 2 handers and /sam.

Follow that, select file, download original.

Notes:
1)i did haste calcs in % form instead of the 1024 form, I will go back later and correct it but the difference is so marginal it wont change anything more then a few 0.0x%
2) Bard haste is assumed to be 25% (+2 march and af3 gloves)
3) any suggestions on what else to add or any calculations i goofed let me know.

I feel this better shows the difference between 24% haste and 25% haste (gear) since it factors in MA or dual wield, as well spell, songs, and JA
