Rick,
I have no experience with ATP, but take the projections and the "promises" they and ALL OTHER flight schools make with a huge grain of salt. They are selling a product, not giving career advice.
If you watch commercials, the medical industry will soon colapse unless YOU come to the Acme School of Medical File Clerking. Medical File Clercking is rapidly growing field.... and knowing that you are helping people is so rewarding Not to mention, You will be working with DOCTORS

In just a few short weeks... blah blah blah.
I instructed at a "Factory" flight school. It was outstanding at producing 71% private pilots (anything over 71% is overkill, right?). IF the student/new private pilot understood they were a 71 percenter and had a bunch to learn yet, they did just fine. NO school can teach you EVERYTHING.
One inherent down side of the super fast training, is you only experience one season in one location, very little bad weather, and almost no decision making..... though, the regionals don't seem to care.
To cut your costs some:
If you plan on getting instructor ratings, start flying from the right seat right after you get your private (and multi). I had some students who did this, and they eliminated about 80% of the usual dual time after the comercial ratings. I even had one outstanding student who scheduled his CFI, CFII, and MEI the day he got his Commericals. I only flew one more hour with him before those checkrides: he passed them all on the first attemp.
HUGE WORD OF WARNING: DO NOT SOLO From the RIGHT SEAT unless you have determined:
1) the flight school allows it
2) the INSURANCE Company allows it and will PAY, heaven forbid, you bend an airplane, and
3) the POH allows solo from the right seat
