Its actually 50.5 % more fuel for exactly E85.
I see a lot of people stating around that 30% mark which I can't seem to figure out where that number comes from.

Using E85 to cover knock without a dyno to monitor torque gained/ loss is not a great idea. Feed back of 98 on road tune/ log is a handy thing.
Remember that the more efeccient a cylinder is, the less timing it will use most of the time so probably means you need to run less timing and more boost

I was just taking a wild guess. I’ve never tuned or ran e85. So it’s all new to me.
yeah stoich E85 is about 9.76:1 give or take, most round to 9.8 and call it done.
I have done plenty of testing on E85 on the dyno and checked this against calculated/adjusted tables vs actual WB lambda and its pretty spot on, actually slightly leaner as E85 is more often E90 from united, its within 2% so well within the margin of error on the equipment and hardware.
