For reference, I was getting 3 track days out of a set of PBR caliper type pads.

PBR Setup
Lifespan: 3 days
$165/set ($55/day)
$660/season

StopTech Setup
Lifespan: 9 days
$285/set ($32/day)
$384

Savings over 6 weekends a year = $276.

The savings doesn't even consider the better feel of the brakes (think a knob with 1-10 in "1" incriments for the StopTech versus 1-3 in "1" incriments for PBR), and the peace of mind knowing they will be the same corner after corner. Also, it has proved difficult to find the limit of the brakes (Even with ABS).
If you are interested in a few other data points, I am getting between 9-10 days on my pads.
I usually try to get a track day before and a half-full day of testing the Friday of a race weekend...so figure 3 days per weekend so I have info on the stock setup but only TT and DE sessions since I switched to the AP Racing calipers when I started with this group.
Metal Matrix
Lifespan 9-10 days
$260 ($28.90/day at 9days)
$520 for a season

EBC Blue
Lifespan 9 days
$199 ($22.11)$398 for a season
I've only just run the Blue's this year for the first time (MSRC, Hallet and TWS). For an endurance pad they did not last as long as I hoped but they are much cheaper and frankly I like the feel of them. EBC is coming out with a race-only compound in October that I might try next year.
