yes, and it is hard to calculate all of these; however this chart helps to quickly identify which teams in a match you should all together avoid trying to start a pushing match with. this chart is not supposed to be a super accurate but it does help. throughout the season my teams drivers only indicated two occasions where they were unable to push someone that we should have been able to push.
for simplicity's sake there are many variable that were cut from calculations, or they were placed in as a constant. its hard enough getting the gearbox reduction ratio from 100 teams, and frankly most just do not know much about their robot.
EDIT: also i would like to factor in weight as it is noticeably the biggest area of error in this chart; however, there is no calculation that even needs the weight of the robot as it is only used in the friction calculations.
