It's all complicated and subtle. The basic idea is that by tuning the table you can get the throttle to open faster at low RPM, but the normal way people do it (which does open the throttle faster) leads to a stair-case effect in the mid-upper range, which can be annoying if you want fine smooth control of your throttle. The idea with the Curve 2300 map is to still open the throttle faster at low RPM, but also be smooth through the upper ranges so that you have good control.
I would imagine a lot of people would think their car feels slower by seat-of-the-pants feel on my map, as compared to a naive tune or those hardware throttle boxes. The idea here is smooth fine control. The stock map is smooth as well, but again has the limitations at low RPM.
Also, I haven't look at this stuff for quite some time. It's still running fine on my car, but I imagine now that UpRev has started unlocking VVEL params, there's probably a lot of new info to work with on throttling as well. Back when I worked on this table, UpRev really wasn't sure what this "throttle" table actually did or what the real parameters its controlling are, it was just trial and error. They must have a better idea by now since it's so tightly coupled with VVEL control.
