I thought I resolved this yesterday on MN, but then spoke to someone last night who thought that 4/5 written in the notes actually means that:
1/5 of the head is in the pelvis and 4/5 can still be felt. i.e you're working down the scale as the baby drops.
I've now found websites that say both...anyone clear it up once and for all?
I know it does n't really matter but I'm sooo excited!
