First time I've tried this puzzle - is it usually quite easy or just this week?
Having said that, I'm stuck on:
9a Mammal meat - there's a kilo out on balance
I have p?r?o???
Many thanks Bullfrog. Perhaps you could help with one other:
20d Old doctor drops boxes - one's very heavy.
I've got HIPPO but I'm not sure why; thinking hippocratic oath and hippos are heavy animals.....
We all have keyboard errors at some time or another. With regard to the puzzle difficulty - IMHO it depends on the setter. Dean Mayer is normally my nemesis.
