How to lower the Magni deceleration on conveyor

Can someone please show me which parameter to change to lower the deceleration for conveyor bot?

I believe the conveyor bot documentation in our GitHub in breadcrumb_learn has a section on modifying navigation parameters, but I would be very cautious doing this. Deceleration of a top heavy robot too abruptly, or turning too sharply can result in tip over and is a safety issue.
