Pumpkin beer low efficiency

Made a pumpkin ale yesterday. Smells great. My efficiency though was really low, like 55% (that's giving the pumpkin a potentially gravity of 1.010 per gal). I mashed the pumpkin and my sparge almost stuck a couple of times. In retrospect I think I should have used more sparge water but I followed the recommended amount form beersmith.

So instead of a 8.5% pumpkin beer it will be 6.5% (or so).

OG was 1.064 was supposed to be 1.089.

Pumpkin has almost no sugar/starch in it, it runs about 3%. So, your efficiency is higher than you think.

Ok, that raises my efficiency to 60%, still low though.
