The proxies in the calculator are not for fasted insulins. A recent study showed upper limit for fasting should be around 5.2. Lab ranges do not apply to fasted horses. Your result is at least suspicious. It's not unusual for horses with clearly abnormal insulins when not fasted, on hay or pasture only, will test "normal" by lab ranges when fasted.
On the other hand, not all overweight horses have EMS and many QHs are easy keepers but rarely have EMS. There are many reasons why a horse can be foot sore.
