PowerSim is accurate and gets the job done for free. It calculates EV, SCORE, and optimal ramp for different strategies. A simplified REKO-F strategy file is attached, along with a hi-lo lite strategy file.

REKO-F: reko_1d_simple.txtreko_1d_simple.txt

Hi-Lo Lite: hilo_lite_1d.txt

You can use PowerSim and these files to quickly simulate REKO-F and hi-lo lite and compare the SCORE for this single-deck game. Using python is another approach.
