I could see the Frigate SA WR being around 1:02-3 not too far from now (1:03 is the best I've failed with the strat Eise used--Alex's strat, and a time that someone like Wouter would target if he plays it). There are two strats that could surely get sub 1:00, although both would be hell (nearly impossible) to get hostage completions.
1: Bug throw, agent hostages, go downstairs, free both downstairs hostages, get out bomb defuser, defuse bomb, warp pipes without ever switching weapons, defuse engine bomb (no pause needed), exit. This is pretty much the current strat but without an extra pause or taking time to kill bridge hostage taker.
2: Bug throw, agent hostages, warp pipes, engine hostage, engine bomb, warp pipes, bridge hostage, bridge bomb. This strat is probably both faster and easier to complete than the above strat. Obviously, both strats would be hell to do.
