How many power points should a custom psycrown have?

[digiman619]

I'm playing a Shaper psion and recently picked up Genesis (basically psionic create demiplane, lesser). I'm in a position where it's easier to craft that it is to retrain, so I was thinking of getting a psicrown of planar travel (basically psionic plane shift). Problem is, while the descriptions tell me how to recharge them (and it's easy enough to do the math to figure out that the recharge cost is the PP cost of the highest level power) , it doesn't say how many power points it should have to start. Any suggestion on how I should proceed? I know this is a "Ask your GM" question, but I'd like to present a ballpark figure.

It’s ML * 50. At least in 3.5.

If you check the Psionic Item rules (https://libraryofmetzofitz.fandom.com/wiki/Psionic_Items#Creating_Psicrowns), the rules for creating various items are at the bottom, and one paragraph of the Psicrown section reads as follows:

Lesser psicrowns cost 100 gp × the level of the power × the level of the manifester for each power stored in the psicrown. Greater psicrowns cost double the cost of lesser psicrowns (200 gp x the level of the power x the level of the manifester for each power stored in the psicrown), and true psicrowns cost double the cost of greater psicrowns (400 gp x the level of the power x the level of the manifester for each power stored in the psicrown). Psicrowns are always created with full power points and have a maximum number of power points equal to ten times the psicrown’s daily recharge rate. The type of a specific psicrown determines its daily recharge rate: 1/3 psicrown’s manifester level (round down) for lesser, 1/2 psicrown’s manifester level (round up) for greater, and equal to psicrown’s manifester level for true.

Okay, I was looking on the Library of Metzofitz and couldn't find this; where on the wiki is it on so I can avoid this sort of gaffe in the future?
