What are you talking about? Every casino "starts out" a BBJ exactly once - when it is first implemented. After that, when one gets hit, the next one is the reserve BBJ.
If you're used to cali jackpots "starting" at 100k, which I assume you mean after one had gotten hit, it's because they've build up reserve jackpots that support that over time. Given time, Parx' jackpot will do the same.
[edit: and for that matter, according to
this site, only 4/23 california casinos have a BBJ which is 100+ right now]
I've seen the formulas being used, but didn't post them because they are somewhat complex. The short version is that first the primary jackpot increases quickly until it hits 200k. The the first reserve jackpot increases quickly while the primary slows down, until the first reserve also hits 200k. Then both increase moderately and a second reserve jackpot starts to build at about the same rate as the other two. So over time you should see the jackpots in the 200+ range, without having a boom/bust that happens to a room when the jackpot gets really big, and is then followed by one which is (relatively) tiny.
