The motor must be allowed to cool adequately before attempting a restart. Noramlly no more than 4 starts per hour, not less than 15 minuts apart are recommended. If you have adequate winding temperature sensors, (no less than two per wdg) you may want to monitor winding temperature.
I am not sure what this has to do with star/delta starter mentioned in the heading of the question.
As for keepig the motor idling, it is very easy, measure the kW of the idling motor/compressor and calculate kW*H*cost/kwh.
Cost of risk on the other hand, is a subjective issue.
