I'd split your trigger's guns. There were a couple of times you were waiting for something besides a web so as to trigger on the next frigate, when they were burning in. Can't really tell, but I'm guessing those mobile drones were really helping with mopping up the frigates when they go into orbit, as you mentioned yourself. Nice run, looks like you're roughly a minute faster than me, gives me hope there is room to improve.

I had considered rigging for warp speed, as sometimes you end up with 40-80 AU warps, would be nice to warp around slightly faster. Might still do that, first plan on logging and recording separate runs with Garde IIs, medium rails, and eventually pulses.
