Yeah, I thought about it and while this way, it doesn't exactly correlate to the way the numbering ended up on SW DeEd in terms of describing the properties of the versions, this way it is much more in line with what the original intention was for the SW numbering:

With SW, the v2.0 was a huge update over v1.0, with better picture quality, more faithful colors and better despecialization. Then the original intention was for v2.1 to be just a small update of v2.0, with some minor fixes and for v2.5 to be the, as the jump in numbering suggests, a larger update with major improvements. But in the course of making v2.1, it evolved into the larger update that v2.5 was originally intended to be, mainly because of the use of 35mm sources for some shots and then v2.5 ended up being the small update, with tiny fixes.

This of course was actually an error and the numbering doesn't really make much sense this way, so I realized that instead of sticking with this erroneous numbering for ESB and ROTJ, it will be better to go back to the way the numbering was originally intended - v2.0 being a big update over v1.0, then v2.1 being a small bug-fixing update of v2.0 and v2.5 being the final version and the last version to still use the GOUT as a source in any way and in the light of recent news possibly the last to use the 2004 transfer as a source as well.
