My example of a bow being forgiving is this.

I have an old round wheel Browning that is 44" long(ATA). My new bow is a single cam that is 32" long. With my old Browning I can be downright sloppy on my follow-through and still shoot great groups. The new short bow has to be shot with a good follow-through with plenty of concentration to get the same groups.

Of course the trade-offs are that the new bow is a lot faster, lighter, and the short ATA makes it easier to handle in the treestand.
