Does anyone know if the rating invite for PC's will increse every time?

My "guess" is that they evaluate the level for the rating invite based on the following:

1. Are they happy with the number of people that attended the last PC?

2. How many people already have 10 PCC?

3. How many people would get an invite at X rating?

Right that's why Amsterdam's was relatively low. They wanted to try and get as many people there as possible.

I would expect a 2675-2700 minimum for Gencon Indy.

That sucks, i just found out i had a rating of 2610 in sealed, but if it keeps going up i won't be invited to SoCal.

It is highly likely that the ratings threshold will continue to increase regularly. As more people participate in sanctioned matches, successful players will earn higher and higher ratings. Also, PCQs and $10,000 Championships will be qualifying more people as they earn invitations by accumulating Pro Circuit Credits.
