The next two are with oversampling of 2, and the last two are with oversampling of 4.
For oversampling of 2, the CH scaler seems to have stopped triggering, therefore messing up the reference signal and making the sync check useless.
For oversampling of 4, though, there's doesnt seem to be a problem when
the gated and reference signals are compared.
