4: All of the start/stop animations have a lead in and lead out based on need for either left or right starts and stops.
What I like is all of the animations are left foot forward biased so if you want the timing to look correct then one will need to lag the animations a bit if in the middle of a right run cycle.
Blend spaces are awesomeness but needs to be clamped or wedged to force it to time properly using the current idle state.
Also a good thing.
The animations I bought comes with FBX source so one can wedge the animations to fit the timing.
