I have a quick question. I have been working on a spreadsheet that would give me an estimated forecast (like in Awakening). I have gotten all the calculated stats (Attack, Avoid, etc) to match the stats listed for my characters, except for hit rating. When I calculate the hit rating for all my characters, the value I get is lower than the one provided on the unit stats (except for my Myrmidon, whose result is actually higher). The following is what I have in my excel spreadsheet:

[center]=ROUNDDOWN(Weapon Hit+(((Skill*3)+Luck)/2), 0)[/center]

I have not included Weapon Bonus rank because none of our weapon ranks are at C or above yet (I was going to add it when I had this formula fixed).

Also, what does Attack Speed do?

Edit: Also, is it a safe assumption that everything rounds down when dealing with fractions?
