Almost all balancers are in the 28-32% range. Most of those are 30%. Tribute is 28%. Purina’s is 32%
Those are all grass balancers.
Alfalfa balancers are in the 10-12% range. Maybe a little higher.
Triple Crown Balancer Gold is 13% - still aimed at grass forages with the higher ca:phos ratio, but they didn’t replace (much) of the protein lost from the soy they removed, whereas Tribute did with their soy-free Wholesome Blends Balancer
11% COULD be a balancer but likely not.
The more definitive factor when looking at those lower protein products is the serving size. 1lb for a 1000lb horse makes an 11% “feed”, much more likely to be a balancer.
Not to be confused with something like TC Lite which is 1-2lb per 500lb body weight
