At this point, 22 of my 24 geldings are now level two. All of them are on week 7, all of them are 333 in their training.

Every gelding is _W_ and training in the discipline the W is in.

My question is, when do they start going up again? Approximately what week would they go up to 4 bars and be showable again?

I know how training works up to week 9 but after that the lines get fuzzy and I don't know when they're supposed to go up.

Every horse trains and levels differently. It's helpful to track your geldings training (note down when they gain a training bar) to get a feeling of how differently rated geldings level and train.

With W-geldings I'd estimate the first ones will gain bars by week 9 depending on individual strengths. By week 10 they should have all training traits at four bars so that's the point where you could try and show them, however I'd wait until their week 11 to be sure. I have only a few W-geldings, so most of my experience comes from E-geldings. They need four weeks of training after they levelled up to be competitive again.
