I the 2 7th I didn’t get the phrase “games moment to moment gameplay decisions”. The keyword “pacing” still does not make it clear for me. I just cannot wrap my head around it, maybe because English is not my first language.
2-4 14th: yeah, I see your point, but you could ask them to distribute gains in a way that they would like the most.
In the reference images I just can’t rate them adequately. I think it’s easier with hourglass figure to decide how much do I like it.
If you’re willing to address it you could render something with http://www.makehumancommunity.org, although I expect it to be too much trouble. I’m pretty sure it would be OK, to just use the BMI graphic for the lower range.
Also, it would probably be easier to rate if you’d used exponential growth scale, with factor f, for which 1 < f < 1.4, probably closer to 1. Otherwise, constant value changes are pretty much invisible on the bigger side and too big on the slimmer.
The last one in the edit with sidenote (only some know) I didn’t get at all.
