Just an update, I've grabbed a new screenshot and it is now saying 147k
per month, which is more reasonable.  The tooling here hasn't been
great.

In the meantime that 'cost factor' has changed to only a 50% discount

The new math would be:  (((147,000 * 0.5 [cost factor]) - 50,000
[ultimate plan free limit]) / 1000 [mins per $10]) * 10 [private for
1000 mins] = $235 per month. 

This is on top of the $600 per month we currently pay Rackspace (the
counted mins only count shared runners). 

Thankfully running 147,000 mins at another provider need not be
impossibly expensive, eg at Catalyst Cloud (just because I can find the
price sheet quickly) it would be ~384 USD (assuming optimal use of 8GB
4CPU instances at exactly 1 hour blocks).  The real world will be more,
but not an earth-shattering difference.

Thankfully this is also the kind of amount we can feasibly ask OSU OSL
to host (I think) or even if we bought at Rackspace (more $$$) it
wouldn't bankrupt us.
