CVCX - calibration with BJA 3 for 6D 4/6 H17 DAS LS

[PinkChip]

Hello

I'm currently trying to calibrate my CVCX using an example from BJA 3 pages 232 and 248, namely for

6 decks, H17, DAS, LS, (no RSA)
4.0/6 = 2/3 = 67 percent pen

$10000 bankroll
Spread 1-12
Play All
4 players at the table

just to find out how CVCX is used correctly (still beginner and quite uncertain about many things,
so I try to set up an example from BJA 3 in order to achieve the same results).

However, I get values slightly different from the book, e.g. a SCORE of 12.65 rather than 13.12,
when I set "Minimum Chip Size":

It doesn't get closer (SCORE of 11.79) when I switch to "Rational Bets":

What do I have to change in the settings in order to get exactly the same results as in the book?
Has it something to do with the "Optimal" and "Practical Wagers" mentioned in the book?
I am particularly uncertain about all these options in the "Simplify" tab on the right of the CVCX Viewer window.

(By the way, why are my PNG screenshots displayed in such a low resolution on this page, compared to my JPG screenshots? I uploaded PNG and JPG files of the same 979 x 677 pixels resolution).

Thanks in advance.
