narration

The initial schedule was equal by characters, but exact GPT-2 counts revealed a 28.0% technical share because code/HTML tokenizes more densely. I’ve calibrated the scheduler to 25.0% tokens per disclosed register (measured shares: 24.97%, 25.01%, 25.01%, 25.01%). This is now the most important controlled test.

narration

Equal target proportions were worse (332.24), so the earlier technical oversampling was beneficial despite the target’s equal composition—consistent with code/Q&A being the hardest register for a 30M model. I’m shifting the experiment from “match target frequency” to “allocate more training tokens to the high-loss register,” testing moderate rather than extreme oversampling.
