BoC fight is the same.
Loses 73s to get to the Parish bonfire from Firelink (which BKH already has at this point)
Iron golem fight is the same.
Loses 3-4s in the O&S fight (estimate)
Saves 2s for not grabbing Hornet ring. (moveswap gwyn loses 2s iirc, so saves 2 instead of 4)
Saves 5s in the Sif fight. (Probably still saves time but not as much as 10 in ultimage)
Saves 4s at Duke's FC.
Seath fight is the same. (could be faster potentially)
Saves 8s on the Catacombs FC.
Loses 2s on Pinwheel. (estimate)
Saves 2s for not killing the crystal lizard before Nito. (Dunno if +4 is enough for 2 kings, +5 is overkill, I remember that)
