OD&D Jousting Table

Found this table in my notebook. Looks like I was converting the jousting table from Chainmail to D&D.

	Level Difference
Chainmail result	-2 or less	-1 to +1	+2 to +4	+5 or more
M*	M	M	G	G
G	M	G	B/U*	U
B	B	B	G	B/U*
H	G	H	H/I	U
U	B/U*	U	U	U/I
B/U	B/U*	B/U	B/U	U/I
U/I	U	U/I	U/I	U/2I
B/U/I	B/U	B/U/I	U	U/I
M A.Phelm	M	M	G	H

* or G at the choice of the attacker
Adjustments (to the effective level of the jouster, I assume)
Heavy Warhorse +1
Plate Armor +1
Light Horse -1
Leather or No Armor -1
Magic Spear + the bonus of the spear

M Miss, no effect
G Glances off: -1 to 3 hits to defender
B* Breaks lance: -1 to 3 hits to attacker, -0 to 2 to defender
H* Helm knocked off: -1 to 3 HEAD hits to defender
U Unhorsed: -1 to 6 hits defender if wearing plate, -1 to 3 if chain
I Injured: -1 to 8 hits defender if attacker wielding battlelance, -1 to 4 if jousting lance
2I Two Injured results.

Hits here is shorthand for hit points of damage.

This was using the Blackmoor hit location system - can only take 15% of total HP as a head hit, very dangerous.

I'm trying to figure out the handwritten notation at the bottom left of the table. it might help to dig out a copy of Chainmail.
