Question about Mana RegenFollow

When I signed up for my Premium Membership and pluged in Character Stats I noticed on my printout the following:
Mana Regen:
2-Base Standing
1-AA
3 Total Base Standing mana regen/tick. Ok so far so good

I started to think hey if my Cleric has a 3 per tick standing what would she regenerate while sitting or riding a horse?

Someone from staff was kind enough to give me this responce and I quote.

"mana regen while sitting is calculated as base(standing+FT item)+ 1 + Meditate / 12 "

Ok my cleric has a meditate skill of 252. No FT items but 1 from AA skill.

BASE ( Standing + FT items ) + 1 + Meditate / 12

The start of the formula the "BASE" is where I got lost and my question to you folks. Does this simple term Base mean....

'My Base sitting mana' = ( Standing base + FT ) + 1 + Meditate / 12 ??

Or does BASE represent another number altogether and if so how do I find out my Base number to apply to this formula??

Or did the guy just mess up and mean to put (Base Standing + FT ) + 1 + Meditate / 12 = Your base sitting mana regen / tick??

In addition do I count my 1 point from my AA as a FT item or would that be included in the "Standing"? Would my AA count towards the FT cap ? Also are buffs effected by sitting or standing?

Thanks for helping me out on this one and please forgive me for my stupid questions I have a feeling it is all very simple once someone fills in some more information for me.

Thank you

What if it was phrased as

2+(FT items)+(aaxp)=standing regen
(standing regen)+1+(meditateskill/12)=sitting regen
Sitting regen = Mounted regen
(current postition regen)+buffs= Current Total mana regen

Also note
The formula I was told was
(standing regen)+(meditateskill/10)=sitting regen

meaning a difference for you of

(2+0+1)+1+(21)=26 sitting mana regen
vs
(2+0+1)+(25)=28 sitting mana regen

Hard to argue 2 per tick over each other... just thought I would mention ther is apparntly more than 1 theory on how it is calculated.

I have never bothered to try to figure it out myself.
