I'm guessing you never read any commercial and residential standard leases, nor commercial contracts for goods and services.
Actually, I write them and enter into them
Nothing like an escalation factor.
We do have floors, just as similar to what is described except
The floor in our case is a fixed dollar amount and if the business makes more than a certain amount is is a percentage of the gross - losses (theft/fire/etc..)
This sounds like a percentage kicker that increases logarithmically, I wouldn’t ever agree to that no matter how good a location it is unless it was tied to improvements that were going to be made that is expected to benefit the business. Example: Adding a parking structure to allow more customers
