How is my carb cycling?

Look training a muscle group once per week will still give you results, just slightly less than with twice per week. It's up to you what you choose.

Besides the MPS argument this is also because there's a maximum amount of effective volume you can do in a workout. If you've already done 6 good sets for chest, the 7th and 8th set are going to have a minimal effect, if any. Or worse: the last sets you're doing can have no additive effect for hypertrophy and only impair recovery.

This is why we recommend against blasting muscle groups once per week with high volume.

I guess I must explain this again. High carb on rest day ti get ready for leg day. Low carb on chest day is irrelevant honestly. It’s a cut anyway lol. Ive talked to competitors about thisz

Your reasoning makes no sense. "I've talked to competitors" does not make a wrong thing right.

Talking to gym bros is actually where bro science comes from. You'll hear all sorts of nonsense in the gym. If you want to learn, learn from competitors that actually know what they're talking about for example Eric Helms, Alberto Nunez, James Krieger, Brad Schoenfeld, Menno Henselmans.
