CERs for "More Psionic Threats"

"It's a Threat!" in Pyramid #3/77: Combat is a system for calibrating encounters for GURPS Dungeon Fantasy games. Here are the ratings for the monsters from "More Psionic Threats" in Pyramid #3/80: Fantasy Threats.

 The values for the Astral Ghost and Astral Spider include Astral Entity, which according to this thread the article didn't include for similar monsters (like the Astral Thing from GURPS Dungeon Fantasy 14: Psi p. 42).

Monster Name	OR	PR	CER	Notes
Astral Ghost	28	56	84
Astral Spider	65	47	113	[1]
Brainworms	16	12	28	[2]
Chaos Ooze	131	311	442	[3]
Tentacles!	35	28	63
Void Wyrm	83	84	167

[1] The bonus from Insubstantiality and Invisibility was halved because the spiders attack by pulling prey into the astral plane, negating these traits.
[2] This does not include brainworm fever since that has no effect within 15 turns.
[3] This is for the common battle form that's given in the article, other forms may have different values.

I'm not entirely sure that I did this correctly, so if anybody is inclined to check my work, I'd appreciate it.
