EEC HARD ALTERNATE/OVERSPEED/overtemp

[de facto]

Hello,

Does your Airline provide you with info on how to avoid low pressure compressor overspeed and or EGT excedance while in the EEC Hard Alternate mode?
The QRH is quite vague on the failure itself and does not provide crews with a way to avoid such an exceedance.

Would flying at lower Mach Number if at the optimum level by reducing the cost index and therefore your Mac cruise speed avoid the low compressor overspeed a satisfactory method?
Would the use of the manual n1 setting in cruise allow us to avoid EEC calculated N1 overshoot ?
For the Go around,would the n1 limit in the QRH be sufficient to avoid a compressor and or EGT exceedance?

Why does the 737 have an Overspeed governor for the turbine but not for the compressor?

Thanks.
