Sorry for the misunderstanding. No, I suspect 10 flights a year is possible.
I doubt 12 can be done without MAJOR changes. 

But given the very poor record of Shuttle performance to schedule, I assert
the burden of proof is on you to show 12 can be done. I'll accept any two
consecutive calendar years with 24 launches.

A DC is simple and reliable enough that 50 flights a year is reasonable
with the specified ground crew. At 10 flights a year a DC ground crew
has lots of idle time so not only are more launches possible, they
will also work to lower costs. Increasing utilization by 25% should
be no problem (if DC works).

With Shuttle, 10 flights a year utilized everything pretty much 100%.
Adding more flights under these conditions means that costs must go up.

Nobody puts people into space just for the hell of it. They are there to
perform tasks. Given that, one can ask what those tasks are and wonder
if there are cheaper ways to do those tasks. We can also decide if the
tasks are worth doing at the price we must pay.

I assert that there are no payloads which must fly on Shuttle and are
worth flying. If you are going to disagree, please do so with a cost
analysis or your arguement will be meaningless.

Don't you see the damage you are doing to manned space here? Manned space
is seen as a boondogle and nothing more than a jobs program for aerospace.
Your astatements that Shuttle must fly regardless of cost only reenforces
that view. You are making it easier for our opponents to harm us.

There isn't a payload in existance today which can't go up on either.

As to being more powerful, only if you are spending somebody else's
money.

This is bogus. By this arguement nothing new should ever be built. If 
you have specific complaints about DC, state them. The arguement 'well
all projects have problems therefore DC will have problems and therefore
it won't work' is bullshit.

More of the same; I'll bet you $50 that it starts flying regularly. Well?
