I’ve said forever that if it looks like a clear slip then continue wrestling where you end up without awarding points to either wrestler. Ref can signal the “slip” to nullify any points being awarded, but if you end up on bottom afterward then you just have to deal with defending the position you are now in. Most slips, at least at a nine international level, are due to a lack of a solid position and technique anyway, so if you don’t want to end up on bottom after then improve on your position and technique.
