Manip Costs

Reset - 18s
Chance of 0 encounters if don't manip one (causing search) - ~2s

Timesaves

0 Encounters on the way up - ~16s (average obviously manip is not going to be optimal for someone willing to grind)
cut through grass on way down ~3.1s
no goalie guy trolling ~1s

Average time save ~2s worth it? probably not but it's fun!
