Narrative:

We were assigned the TAMMY4 RNAV arrival into mem. After meeting the crossing restriction at tammy we got a new assigned altitude down to 6;000. We were a little unclear about the airspeed and were at rocab around 20 KTS faster than what is listed on the arrival. To add to our workload we had a GEN2 fail just prior and we had weather on the arrival.
