Print speed fine tuning

Hi, first, I would like to describe my situation…
I am printing my version of the Airless Basketball. Mine is a fully enclosed ball with walls and I placed 2 jingle bells inside. I see that with Amazon Basic TPU and 6 .5mm walls. 100% infill. I have my ball shelled to 3mm Wall thickness in shapr3d. I am dialing in the speed settings. At 100% speed using the Generic TPU profile it is under extruding. In silent 50% as a test while printing it is now only partially under extruding. I would like to dial in a number like 35% to try that. This is a much quicker way to set and test my project. It does not seem that the automatic AI flow rate calibration is smart enough to adjust for this issue. I WOULD REALLY love, love ,love if the AI could first adjust speed better to keep speeds within a printable range. And if the AI looking at my object detected A considerable under extrusion which I think it is supposed to be performing on every print. At least within a rage. To adjust print speeds then this would be a HUGE upgrade to Bambu Studio and my X1C. Maybe it can not do this through AI because AI can’t adjust that fast. I love these type of AI feature and that is what I bought the x1c for. Please try to implement. At the very lest I would like to dial in real time a specific speed value to manually test and adjust the speed. I do not want to have to go into slicer setting adjust speed, try, adjust speed in settings, try and so on. Way to much frustration and waisted time.

Same situation here.
restarted a production volume project and each print is around 12-36 hours
CC3D 72D TPU based project.

Needless to say, it’s getting tiring restarting prints to adjust base speed
2nd time 15 c.u. mm/s and 50% is too slow, 100% is too fast

I have another machine where I can just adjust the speed by a percentage and dial it in on the fly, saving $$$ of initial prints by continuing once the speed on the new material is dialed in.

Then on subsequent prints I just use the rates calculated by the offset adjustment I used during the initial test print.

Would make dialing in things MUCH easier
