Well, the jury is still out on this! It seemed to be very generous the first night, and I earned 2.5 BPs at work , then that went upto 3 by the time I had drove home. It should have a standby button!
But,last night,it was a lot meaner,and I thought it was being very accurate,time will tell.
I have had about 5 coffee's, 2 toast, but i showered then had an SP, 15-5.25, most impressed!
Still dreading this bank holiday though, saving loads of points!
