Your pack seems to be "false peaking." Did you perform a C/10 slow charge when the pack was brand new?
An initial C/10 will ensure that the pack's cells are balanced. Just charge at 150mA to 175mA for 20-24 hours. All new packs should see this treatment before the fast charger is used.
Once you get a full charge into the pack you will be able to see its real performance. It should take 1800mAH (or more) to recharge that pack when it is exhausted. A 74mAH charge is not close by a long shot.
BTW, it will take three or four cycles before the NiMH's full capacity is realized. But that is not the source of the problem in this case. Get a full charge into the pack and you will be good to go.
