Great read. Thanks. Since replies on medium do not allow to insert an image, I wrote the reply as a separate post with my version of the Bird scooter rental financial model and unit economics using charging cycles as a measure unit for P/L. Based on my assumptions, basically, every day the scooter survives after 86 cycles, 258 rides, or 43 days it generates revenue.
