If carb consumption is low enough to consume it, doesn't matter. But the ceiling is higher for 1:1. With 100g/hr, you might already be around the limit (possibly even a bit over) for 0.5:1.

I already consume a lot, and I like my mix.

But wondering if there’s any advantage to keeping same total carbs and adjusting ratios.

I doubt I can consume many more total carbs - I’m typically 130-150g/hour

Total carb intake matters more than glucose:fructose ratio, by a lot. The glucose:fructose ratio optimization problem is imperative for most folks to get anywhere near your carb intake rates. If I were you, I wouldn't change a thing.

That’s what I suspected

Thank you

Just attaching my name to this worthwhile advice! ;)

There's not much special* about carb ratios beyond the fact that it can push up an upper ceiling for carb intake / oxidation.

If you are not having any issues with absorption (GI Distress, Bloating, etc) then you're likely fine.



*There may be nuances- but they likely matter less in the overall scheme. E.g. fructose results in more metabolic thermogenesis than glucose.
