Take note, that I amended my comment above since you last saw it regarding MINT. It had a GFPR max that was not being honored with a calculation. My main point that GFPR is significantly too high IMO still stands, but I’ve corrected the information 
Much thanks for screenshots 
You are absolutely correct that at 10.00000001 (not 9.99999) there is a bump I did not notice because the train is switching tracks. The pre 10B track is focused on getting to deflation by 10B with minimal hit to the servicers, while post 10B then on growing servicers while still maintaining a deflationary projection.
However, the transition should be fluid, so I updated cell B23. Now it works without any jumps.
Thank-you for pointing out the issue
