How to properly run Sysid

First of I’d like to begin by apologizing for not being able to provide pictures of the graphs themselves so I will describe them as accurately as possible.

I was going through all the sysid tests and everything seemed to be fine until I analyzed the data. The acceleration vs. Velocity and timesteps vs. Time graphs looked fine, but the other velocity vs. Time ones were clearly wrong.

The quasi static vs. Time graph has one orange line going up diagonally to the right then there was a gap in the middle and there was a new orange line going diagonally down. As for the dynamic Vel vs. Time graph, there was one almost completely vertical green line to the left, a huge gap in the middle, and then another vertical green line on the right side.

I’m honestly at a loss for why this could have happened because the test seemed to have run fine. Any ideas? Does anybody know for how long each test was supposed to be run for?
