Marking a putt can be psychological advantage "I am closer, so it is an easier putt", or a definite advantage...my lie 'as-is' may be just a bit too far for me to just reach over and drop my disc....marking my lie may get me close enough that I can drop the disc in instead of throwing it in.

I rarely mark for approaches or second throws on long holes (unless it creates an advantage by giving me space from an impediment), but regularly do for putting.
The reason is twofold:
1. I do feel more confident knowing that my putt is nearly a foot shorter than it would be if I didn't mark. Even if that only results in one extra made putt every couple rounds, that is still an advantage.
2. I always putt with a disc in my spare hand. So often I will bend down to mark my lie, pickup the thrown disc, and hold that disc in my off hand while putting. If I don't mark, then I have to grab both of my putting putters so that my off hand has something to do. It's almost easier for me to just mark. And yes, I know I'm a headcase.

The distance where the extra 8" from marking a putt makes the most difference is at the threshold of where you are not quite certain of making the putt. Usually a little less than 20 feet out. At that range, it can increase your chance of making the putt by as much as 7%.

This matches my anecdotal experience. The area that I feel like 8" makes the most difference for me is between 15' and 30'. I'm curious though, where did you find the 7% figure?

I feel like that 8" makes a bigger difference in bed.

At really short ranges, when you are absolutely certain you'll make the putt, marking won't matter. However, the relative change in difference is greatest when the distance is shortest.

I quantified that using a simple, but data-based, model of putting where the success rate goes down with the square of the distance. The success rate is capped at 100%. For the 980-rated players in the study, that happened at 18 feet, one inch. 18 feet, 9 inches is 3.7% farther, 1.037 squared is 1.075, and the inverse of 1.075 is 0.93. So, don't mark and make 93%, or mark and make 100%.

Obviously, the success rate doesn't really go up to 100% at any specific distance, let alone 18 feet. So, 7% is likely overly high for real life, and there would be some gain by using a mini at distances less than 18 feet.

As for the other end of the range, at 32 feet about one more putt per 72 attempts would be made from 8 inches closer for 980-rated players.

Good rule of thumb: between gimme range and the circle, use a mini.

This is some fine pretzel logic right here. I think the only measurable increase in putting % would be the range at which you can drop the disc in the basket + 8".
