Dispensed with changing all to loop. That's easy enough to do if you wish. Added set recent best at beginning of script and restore recent best after each stepsize finishes. This should work better if you have bands set or if you want to run at lower CI (just set CI with the slider before running).

Have found this script very useful for quick evo and for changing from low wiggle power to higher power (after Cut and Wiggle :))

recipe runs LW on all stepsizes between 13 and 2, changing from long to short to long again, thusly:

stepsize 13,2,12,2A,11,3,10,3A....
