That would be it exactly.
Why buy a 787 when it can be won in "like the wind" and when you complete 75%.
In fact if you take on "like the wind" when you are at 74.8% you should get them both at the same time.
If you leave it for the last race in "Professional" and you happen to be at 74.8% (A whole lotta skippage goin' on) You could hit the "trifecta".
