Here's an interesting take on all of this.

I have two ASIO drivers on my machine. One from MOTU with my 828MK3 interface and a second directly from Steinberg on my Yamaha Montage 7. Shutting the system down completely between ASIO driver runs and looking at the results over 10 runs of the RB "Test Audio Performance", the Steinberg driver runs between 1350 and 1450. The MOTU ASIO drivers runs between 1500 and 1550. It appears that the type of ASIO driver makes a difference.

Here's what makes an even bigger difference...sample rate. Using just the MOTU ASIO driver at 24 bit / 44.1, I get the numbers above. But, if I switch to 16 bit / 44.1, potential tracks shoot much higher, running between 2325 and 2430.

Switching over to the Steinberg ASIO driver, at 16 bit, gives a narrower range, from 2000 to 2020 but still higher than the 24 bit range.

So from what I'm seeing how the driver is written, how its integrates with your interface and sampling rate seem to make a difference.
