The clip you showed about a light-hearted contest in a kiddie pool with applesauce (confined slippery space) was not a valid way to compare weight v. stamina. While smaller females may be more agile, the heavier ladies can wear down their opponents. But having watched several catfights IRL and a few wrestling matches, it seems that the more aggressive woman, regardless of weight advantage, usually intimidates her opponent and eventually wins. Having said that, I find voluptuous women extremely alluring and always want them to dominate their smaller victims.
