At least i can agree with the observation that the there seems to less rewards. For me i did assigned more CPU into my projects, but i received less coins. I thought this was related to more competition since more and more people joined the network. Could the observed effects are beeing related to more people joining the team and crunching, but not being able to stake (solo mining with low amount of GRC)?

As there comes more competition in the project your magnitude will drop, that is how it works. But what is unclear is why the RAC itself drops.
