I am inclined to agree, based on Crowbar's ring record. It's most likely a typo. Besides, if the last digit isn't a zero, then something went wrong with the speed score, which means he would have collected at least 500 rings under 2:20 or 2:30 or whatever the time limit for score is on that level, which according to Crowbar's comment on his Blaze ring record for that level, takes nine minutes. :/
