The best way to check your coil is to set your gain to 15, turn Tx Boost on with the coil in the air (not on the ground or around other metal). If you don't get an overload (audio groan, display status), your coil is good. That is what the detector is designed for - not overloading at the extremes. The probe (zoom on the sensitivity live control) that suggests a recommended gain is not a good coil test - it was never meant to be a coil test. But, for the most part your coils should be above 8 on the recommended gain (in air). But, the 6x10 tends to read around 7 if I recall correctly.
