There are guys using Evans here at the shop that are getting as much as 28 degrees F cooler (digital coolant gauges) which is a lot
EDIT: I would not recommend Evans Coolants at this point as it is epxenisve (+$40/gallon) and your entire system musty be flushed with it to remove the old coolant. Also leaks past water pump seals & head gaskets on customer bikes. Smells bad. Emergency top-ups can only be with Evans, not water or coolant commonly available
of course I have the H2W 2nd fan kit & the lower thermostat on my bike really works to keep the temps down, and quickly. Fans go off pretty soon after coming on compared to one fan where it might run for minutes depending on just how hot (& slow-going) things are
