I know guys that do it like that. I prefer to run it from INB to INU, stop on the limit, jump it out, than hit the stop ring. So I test the directional limit at the same time. Also not generally a good idea to run a car from the machine room without door locks or safety circuit. And not that this is what you asked but if you’re troubleshooting a down car it tells you nothing that it will run from W to R/M.
