Get as much percentage as possible with all glitch techs, except:
Back-dash+DHR, Thrust+DHR, and Sinking.
This eliminates Extended wall grabs, Bat-ups, and any shifting beyond the initial shift in S4R.
Small edge-travel is still posible with dive-kick+DHR, and it may be possible to shift the Chapel bell-towers with a perfectly timed dive-kick+DHR; but no one has tested this(?) and for this challenge it will be dis-allowed.
I feel that before all forms of edge-travel were found, that this game was only semi-broken. And afterwards, the game seems so broken that we've questioned the legality of a tech involving back-dash+DHRs, since it's inception.
Btw, this is a race so you'd better hurry and get started!!!
