Sadly, no, Fix-it-Friday is only for bugs…things that are not currently working as originally designed/intended. Anything else is considered a “Feature request” and does not qualify for Fix-it-Friday events. Even if a feature request gets the most likes in that thread, it is automatically disqualified from the Fix-it-Friday event because they are solely looking for the “highest-impact bugs.”
As stated, the wishlist is for feature requests, and Fix-it-Friday is for bugs. BUT likes on wishlist requests do have a big impact, as does activity, such as us commenting on here recently to show there is still interest. But other things also matter, including how easy to implement it would be, cost, resources, how many people would use it, etc. So something easy to implement can sometimes jump the line even if it has fewer votes like this. So there are multiple factors that go into it. But Fix-it-Friday is not one of them since it’s not technically considered an unintended high-impact bug.
Still, you have a good idea. It does seem like they could just lower the minimum speed range to make this work. Hopefully that means it would be a fairly easy thing to add. I don’t know how it’s coded or setup, but seems like a reasonably straightforward thing to adjust.
