Default Custom Prime settings for single core stress testing?

I'm writing a stress test script that can be used to stress test the single core stability for Ryzen's boost functionality (i.e. Precision Boost Overdrive in conjunction with Curve Optimizer, but theoretically it should also work for Intel CPUs and their turbo boost functionality, although I have no way of testing that myself).

Prime95 is still the best stress test program I was able to find for this, but I'm not 100% sure about the settings I'm using. I might not have fully understood all of them or maybe forgot something important.
The way the stress test works (or at least should work) is to only stress test one core at any time, and either use one or two threads of this core, depending on the user's choice.
So far it seems to work pretty well, but maybe there are still ways to improve the settings. Cheers!
