This question has turned out to be surprisingly interesting. Like Sergeant Schultz and Jon Snow, "I know nothing"; however, it seems to me that this is a technical question likely to have one correct answer.
Best Standard is on to something.
That's logical, but I can't see that pulling the chain down is necessary to remove the slack from the top run of the chain; that will surely also happen as you push the thing up. All pulling the chain down will do is ensure you get a measurement of the total slack in the chain as the sag in the top will ever-so-slightly reduce the actual slack in the lower run.
Having looked at the pictures here, on the bike and in the service manual, I don't think any comfort can be found in an analysis of the pictures. All those arrows are telling you is that there needs to be slack in the chain of 25 - 35mm. Sort of like marking the ends of a line in an engineer's drawing of a building. They don't tell you HOW to measure it. Neither does the Owners Manual, "Check the drive chain slack", nor the Service Manual, "Check the slack in the drive chain ..."
I can't see any point in asking a mechanic at a Honda shop as they're most likely to do it however they were taught and that won't necessarily have been by the Honda guru.
I can think of one last question: Does anyone have the Honda Motorcycle Common Service Manual? I know our leader, Guth, has one as he referred to it in a post the other day. Lord Popgun, do you? Anyone? If so, could you please, please consult it and see whether it says anything at all about HOW to measure the slack in a chain?

My summer job during high school and college was at a Honda and Harley (AMF) shop. This video shows how I was taught to do it back in the 1970's... and I've been pulling down before pushing up ever since without any issues. Pulling and pushing takes the slack out of the upper run of chain, since total slack is normally split between the upper and lower runs (when in neutral) due to the weight of each run.
