A yield is when you pump your milk and see how many ounces you're producing. It may be that you need to feed him from both sides.
I asked about the cluster feed because from your routine it didn't say Eat at 7.
Cluster feeds are for the nights not mornings.
I definitely think you should keep the cluster feed at 10 pm, but let's see if you can get him back to sleep at 1 without feeding. Try shh/pat until he falls asleep again. And I think maybe if you could start to push that 5 am feeding back little by little and have it slowly merge with the 7 am feeding. Move it by increments of 15 mins every few days.
It may be a good idea to start this weekend and have dh give you a helping hand with the 1 am waking
Let me know how it goes
