This is well thought out and deigned dishing tool. 1.) You can use it with the wheel mounted in a Park TS series truing stand. 2.) You can use this with the tires still mounted to the rim. This is a big time saver, and important with tubeless when you don't want to remove the tire if you can avoid it. 3.) Its a sturdy tool, and does not deflect. 4.) You could use it with skewers still installed but its not a big deal to remove them, so I don't really see the use case for this. 5.) Its more than precise enough for most wheel building/truing as long as you aren't trying to go for extreme tolerances which require special setups anyway due to errors introduced by the tolerances of the hub, lock nuts, axle threads etc...
