That's kind of like Nigel from Spinal Tap's argument that his amp goes to 11.
I doubt that internally Lyft stores your score on a scale of 1 to 5. It's almost certainly derived from a bunch of other data, or at the very least stored as a floating point number. You can approximate whatever curve you like with either, and then just round.
I'd believe that Lyft doesn't currently have a power law curve, but the 1-5 system isn't what's stopping them.
- dnautics 11y agoI know Uber stores as a float. Lyft probably does not since it's averaged over 100 rides. Integer math is easy! Also you can't mathematically have a power law over (1..5)
- klodolph 11y agoYou can't have a power law over 1..5? Yes you can. Power law works perfectly fine with finite ranges. It works perfectly fine with discrete values as well. The only question is how accurate a power law model would be in this case.
- SixSigma 11y agoHow about : 100-90% you get a 5 90-75% you get a 4 75-40% you get a 3 40-5% you get a 2 5% and under a 1
