That's not even approximately the correct ceiling for the 182.

The chance of reaching 100,000 ft is not the only issue.  

Things pilots care about include:
 -- RPM as a function of altitude, prop control, throttle, etc.
 -- MAP as a function of .. .. 
 -- Rate of climb as a function of .. .. 
 -- Level-flight speed as a function of .. .. 
 -- Mixture requirements as a function of .. .. 
 -- EGT as a function of mixture and .. .. 
 -- fuel-consumption rates as a function of .. ..

Evidently "ok" means different things to different people.

 *) Some FG users don't care much about the aforementioned items or
