Watched Channel 10's showing of this. It was much better than expected, even with the huge discrepancy in times for the best driver down to the worst driver.
I'm contemplating going to Eastern Creek to see it now.
re: Power Boost.
As far as I can understand it, it is a button the driver can press a selected number of times (same for each driver for each race) that will lift the RPM redline of the engine so that they can get a kick in power. Once activated, it remains active until they lift off the accelerator, so it isn't governed by the number of seconds for each boost, but how brave the driver is in keeping his or her foot on the accelerator for a lengthy period of time on the track
