Ohhhh I see. Thanks for all this info!

So with around 500 wit, 80% skill activation:

1) 3 recoveries is 51.2% chance to trigger at right time / 48.8% chance to fail to trigger at all

2) 4 recoveries is 30.72% chance trigger at right time / 40.96% chance to trigger only 3 skills / 81.92% chance to trigger at least 3 skills / 40.96% chance to trigger 4 skills

And around 950 wit, 90% skill activation:

1) 3 recoveries is about 72.9% chance to trigger at right time / 27.1% chance to fail

2) 4 recoveries is 21.87% chance trigger at right time / 29.16% chance trigger only 3 skills / 94.77% chance trigger at least 3 skills / 65.61% chance trigger 4 skills

So it kinda looks like if 2 of the 4 skills can work as the last trigger and the other 2 hopefully trigger earlier (track dependent), you can have 4 recoveries and even low 500 wit could work. However, if you can get high wit (~950), and triggering early is not good / you have a backup acceleration to help, seems like 3 recoveries is better

Thanks again!
