Might depend on how those miles are ridden. Stop-and-go through lots of traffic lights or stop signs will bring the mpg way down.
I did my break-in mostly on roads with no lights or stops and got 64-67 mpg for the first 600 miles (haven't measured it since then), and that was on mountain roads between 6,200 and 9,500 feet elevation.
I didn't just keep the rpms at 7,000 or lower, either, but took it up to 8,000 or 9,000 for short distances periodically.
