It seems to me that that parking companies are capping earnings....my data suggests that after reaching a certain amount subsequent earnings drop off. Now I suspect some quite interesting algorithms for dynamic revenue share. I'd do this if I were a parking company it makes sense. If customer A is earning X and expects, why pay more. Now, my challenge is for any parking company to be transparent about their earnings model and break down the revenue split for a portfolio of active names. I'll be waiting guys!
