I had a similar problem as the OP. I am running a Play by Post BRP pulp adventure, and to speed up the combat back-and-forth rolls between players and NPCs, we are using the Resistance Table to compare relevant combat skills. There is an Optional Rule in BRP about this (page 174 of the 'Leonardo cover' book), simply divide the opposed skills % by 5, rounding to the nearest whole number, and compare the results on the Table. (This also makes it possible to compare a 3d6-based characteristic to a Percentile-based skill). So, (attacker Brawl 55% vs defender Dodge 22%) becomes (11 vs 5) resulting in a 80% chance to hit that takes into account the target Dodge. It's probably a bit broken applied to combat, but it's working fine for our pulp game. I even added the % values to a customised Resistance Table spreadsheet for my own usage.
