leaving the elevator above Lemm down after the very first visit lets you do a fun inv drop, skipping the any% lever on the right side, and saves about ~1.2s over good execution of the regular strat.
if you hit the inv drop but hardfall it loses ~0.3-0.5s (so still saves time), if you miss the inv drop there's a very lenient backup which loses ~0.5s over good regular strat execution, but is completely consistent and makes avg loss with the strat negligible.
