Agemegos, are you still around?

I know that you do not plan to do any more work on this project than the amount you've already put in. But may I ask you for a few clarifications about the program, and the changes you made to the World Design Sequence?

You listed some issues here:

And here you mentioned changes made due to errors:

Does the SJG policy leave room for you to say which formulas have errors and what mathematical changes you'd suggest we make when manually using the design sequence? I want to be able to modify the Sequence when using it manually, using corrected formulae for climate, tidal braking, orbit eccentricity, and red giant luminosity.

In particular, do you have any suggestions for modifying the climate table and/or atmospheric pressure equations to keep water liquid on a planet surface? I've been trying to modify it to do so and even for garden worlds it doesn't seem to hold up in all circumstances, especially at high temperatures where the pressure drops below boiling. Is there a modification that will prevent it from generating the icehouse worlds on the wrong world type?
