Approximate a veteran-vs-novice table by naming what each seat does: e.g. loose keeps + tap-out interaction + generic plan for the novice, strict keeps + cEDH interaction for the veteran. There is no skill slider — a number would be a free variable with no source; every difference here is a policy the readout states.
