All decay+fees divided by 2 on Calypso for Calypso born Avatars. (MA 50%, CLD/players 50%)
All decay+fees divided by 4 on Calypso for Immigrants (non Calypso born avatars) (MA 25%, CLD 25%, PP origin 50%)
All decay+ fees divided by 4 on Any other planet by Calypso born Avatars. (MA 25%, CLD 25%, PP 50%)
All decay+ fees divided by 0 on any other Planet by non Calypso Avatars. (MA perhaps gets a default cut(unless they consider the purchase of planet the alternative to fees), but CLD do not)
I don't think that can be right. Firstly I think MA gets 50% regardless of where it is (unless space in which case 100%). Secondly, CLDs were only equivalent to half a planet sale so whenever CLD gets something, PP Calypso must get something too.
So I'd guess:
Calypso for Calypso-born: MA 50%, CLD 25%, Calypso 25%
Calypso for Immigrants: MA 50%, CLD 8.33%, Calypso 8.33%, PP origin 33.33%
Other planet by Calypso-born: MA 50%, CLD 16.66%, Calypso 16.66%, PP 16.66%
Other planet by non-Calypso-born: MA 50%, PP 16.66%, PP-Origin 33.33% (PP may equal PP-Origin)
Space: MA 100%
I'm going by tbarmike's comment above though. It seems to me that is crazy unfair on the PP that the activity is on, especially in the long-run if the player essentially has pretty much permanently chosen the new planet over Calypso (and may hence not still be playing if it was still just Calypso). So if tbarmike has it the wrong way round it'd be more like:
Calypso for Calypso-born: MA 50%, CLD 25%, Calypso 25%
Calypso for Immigrants: MA 50%, CLD 16.66%, Calypso 16.66%, PP origin 16.66%
Other planet by Calypso-born: MA 50%, CLD 8.33%, Calypso 8.33%, PP 33.33%
Other planet by non-Calypso-born: MA 50%, PP 33.33%, PP-Origin 16.66% (PP may equal PP-Origin)
Space: MA 100%
Eitherways, it'd be nice to know for sure. Are we all just being lazy, or has MA never published the info?
