Got it, thanks for answering my question so quickly.
We are playing German Fighter unit in the Battle of Moscow Campaign and we plan to complete our campaign in Germany, 1945. We thought it would be neat for us to have promotions to look forward to later in the war but the 10-25-60-100 sortie requirements are being met really quickly by a lot of us and some of us have gone from Obfw. to Olt. in less than 3 months of game time. So we were just wondering if we can increase the requirements to slow our progress and spread it across 1941 - 1945.
As always thank you so much for all your work in the PWCG, it really makes the game so much fun for us
