Emphasis added by me.Except that your reasoning requires the assumption that there is a contradiction between the table and text (so that you can invoke a further piece from the DMG errata) - that is an additional two steps required in your argument, and therefore a substantial point against it as the simplest answer is most likely the right one.
If you look only at the player's handbook, then it is definitely more likely that the interpretation that results in no contradiction is the correct one. I would ask how much more likely, maybe 70/30 or 80/20? Heck, maybe even 99/1, meaning that if you read 100 different ambiguous rules then your method of analysis would result in the "rules as intended" answer 99% of the time. Your method of rules analysis is generally sound and is more likely than not to arrive at the "rules as intended" answer.
However, there is evidence outside the player's handbook that suggests the player's handbook contains an error and it should not have said standard action. Even if your method provides the right answer 99% of the time, it will still be wrong 1% of the time.
