Hey MGM specialist, take a look please

Could somebody tell me what's the "ms" in the breaking and acceleration parameter on the programing table.
On the Castle programing template, the acceleration is easy to understand because acceleration is explain in "low", "medium", "hard", "very hard", etc....

But MGM name it with "ms", as .13, .86, etc....

What this "ms" does it mean

How can i know what this number does it mean???

I realy not understand.

I know this is in relation with trottle position, but WHY????????????
