I can confirm that we are seeing same behaviour in our app.
we can usually serve everyone with 6 instances, but in the last 6 weeks 
something has been changed and even though at any one time we have 6-7 
instances, we have 1000 warmups a day.

so definitely something caused the scheduler to change behaviour as we only 
had 10 warmups a day before Oct.
We've not made any code changes to our app in 5 months.
