i say 4:20-4:25
why didn't you just run a mile, instead of that epic session?
You'd know, and you'd have saved a lot of time. Certainly it would have been less that 30 minutes
4:20-4:25. faster if you have a good open 400 time
4:32. Too much rest. I know guys who do 16x400m with 1 min rest at 65-67. This is assuming a good base and mileage.
