Roughly how much stronger?

[Rebel]

1. Much improved time control, especially the game in x levels.

2. Added permanent brain, also known as pondering.

3. The engine has increased somewhat in strength. We estimate an overall increase of 5-15 elo but on game in x levels 20-30 elo.

Roughly how much stronger?

My estimates always seem to be a ways off when I compare the results of my tests to the ones you guys get, but I'm expecting/hoping for around 2700 CCRL!

This was the time control I used. Do I have to use margin of 1000ms?

Yes, in our testing we use a timemargin of 1 second in cutechess.
