I heard a bloke down the pub say you should always ise 70:30... I know the same bloke down the pub that claims never to use his rear brake. Never seen him on his bike though. That's kind of me, yes all this 50/50 70/30 is bull with differing discs calipers etc you'll never know, but I don't use my back brake, I know others that don't other than as s handbrake, I only actually use it on the move to clean up the disc so it won't fail the mot. Yes I know you shouldn't tell noobs that they shouldn't use it but as you gain experience you will learn what works for you. I thought before remove my rear brake I could go on a rideout remove the front I am not going anywhere.
