Your speed for the work is too low, your speed for the rest is too high. If you can run for 10 minutes at 90% MS, then whats the point of doing 1 min intervals at that same speed?
I would suggest
A. Use an incline on the treadmill of at least 2% no matter what you are doing.
A2. Perform a dynamic running warm up prior to treadmill sprints (after you 5-10 min jog).
B. Find a speed you can maintain for no longer than 1:15, run that for 1 min, then drop it down to a walk for 1 min. Repeat that 10 times.
C. Your warm-down period looks good. Stretch afterwards.
