Fixing a ceiling in turnover clause rental agreement

Q: I read the fatwa regarding rental based on percentage of turnover being impermissible. I would like to query further that in the case where the landlord fixes a maximum amount for the rental, so that in the event of the turnover being a very large amount, the rental will not surpass the ceiling that has been fixed for the rental, will the ruling change in anyway? Most commercial properties work in this way and many tenants request this type of an agreement and are pleased with it.
