There is NO data that proofs that bacteroides must be below 10% but i too think 50% is a bit high. The gut biome differs hugely between even healthy persons, and diet can completely change the composition of it within days.
The perfect ratio is a myth. The american gut project has tried to find the perfect composition and failed, there is none.

Some are not possible pathogens and some are pathogenic if there levels are high enough.
It seems to me the relative ratios of the "good to bad" bacteroides would be more important than the overall percentage of bacteroides in the gut. Just a thought.
