I think you meant power level, which is determine by your level, stats, items and probably some more we don't know about.

And yes, if your power level is too high compare to your opponent you will most likely get less experience. But I'm not sure how much 1-2 work experience level will affect that score. Especially if levels are worth more at higher levels, then a level 5 work exp, for example, wouldn't influence your power levels much compare to level 20-30-40 for other stats.

I hope that's what you were looking for.
