There shouldn't be a linear increase in support requests with a larger customer base.

As your product scales to more customers, the percentage of support requests generated should be going down as you improve your product and support documentation based on existing customer support requests.

This ("shouldn't be a linear increase in support requests") is true some of the time, but not all of the time in all lines of business. Make a thing foolproof, and the world will go on generating greater fools, you will see a greater variety in weird requests or bizarre expectations, etc.

The number of requests may scale linearly, but the number of actual issues won’t.
