M = Meditate Skill
L = Level
FT = Mana Regen

So Mage guide from 2004 says Med / 12 = Regen.

(2) Meditate Skill

Beginning at level 4, necromancers gain the Meditate ability. While you are sitting (or riding a mount), you receive a mana regeneration bonus equal to 1/10th of your Meditate skill, to a maximum of 25 mana/tick at Meditate 252.

n.b. This skill is level-capped until it reaches 252. At each character level, the maximum rank you can achieve is equal to [(level x 5) + 5]. e.g. At level 12, a character's maximum Meditate rank is [(12 x 5) + 5] = 65.

Necro Post from 2003 says Med / 10 = Mana Regen
