Quick question about Ascendant: With the scaling you're using (each point bing a doubling), how do you represent someone being stronger but not twice as strong? Is there room for fine tuning the differences between the fighting skills of Batman, Nightwing, and Deathstroke or the strength of Black Adam vs. Shazam?
No, sadly, fine tuning is limited by the logarithmic scale. Each supermetric point is a doubling so there is no direct way to represent someone who is stronger but not twice as strong. (Of if there is a way, I didn't find it.) The game allows you some indirect methods to represent differences, e.g. you can change the number of Hero Points they can expend on tasks, allowing one character to have a burst of strength the other cannot, or can make a character "Tireless" or "Easily Winded" to change their Might over periods of time, or can use skills to make one character or another better in specific areas, etc.
But you're limited to about half the granularity of a D&D5E range. A Strength of 18 or 20 (+4 or +5) matches to Ascendant 5, 14 or 16 is Ascendant 4, etc. I thought about switching to a ^1.5 logarithmic scale to address this but it was extremely counterintuitive for players.
