I think a lot of it has to do with the time of year & vacations/holidays, more than any issues of mediocre racing or the like.
(That said, I'm the mediocre racer... so maybe I'm not the best person to judge. LOL)
I love recommended garage racing.
"The Sofa Drivers" even tried racing the vintage Fiat from the Recommended List... on Monte Carlo. hahahahaha
Though yes, I get frustrated too. It's very hard to organize racing with time zones, & holidays, and people you don't know what their situations are... It gets very complicated.
And I think 19L that you do VERY WELL all things considered. You obviously have organizational skills. And decent people-skills if that's the right way to put it. haha.
