Air carrier pilot reported that the 'climb via' verbiage used for climbing instructions is flawed.

Narrative:

The correction that was just posted about the climb via phraseology was the last straw. Maybe I'm just not that smart; but this is the opinion of one 43 year; 29;000 hour pilot. The repeated instructions on the climb verbiage should be a hint to the FAA that the human factors on this process seriously flawed. The many similar variations are distracting during the phase of flight where we are climbing; accelerating; cleaning up; navigating and changing frequencies. Having to stop the mental process to try to understand the instructions at this critical phase is an unnecessarily threat.
