Could be a couple of reasons depending on application or goal. If you wanted to turn a smaller pitch prop for greater acceleration, the additional rpms would allow decent top end numbers where the consumer motor would hit the limiter sooner. Additionally, 700 rpms when plugged into a prop calculator will yield greater top speed assuming you can turn the prop to the 8200.
Example:
32p prop, 1.87 gears, 10% slip, @ 8200rpms= 119.6 mph/192.47kph
32p prop, 1.87 gears, 10% slip, @ 7500rpms= 109.4 mph /176.06kph
