EC2 t1.micro overprovisioning

I was playing with a bunch of instances today and trying to keep budget low as I was pushing upwards of 20 EC2 instances, I spawned a t1.micro instance to generate some load on my servers.
This is what I got:

Roughly 87% steal!

Meaning the hypervisor is gently telling me to go to hell 9 times out of 10.

There must be a bunch of these micro instances running... Actually what I think is happening is amazon must be using the t1.micro format to try and fill the gaps on otherwise underutilized racks. In the end, the quest for maximizing resources ends up with a massively underwhelming experience for this instance type.
Fortunately, the rest of the infrastructure is second to none.
