Did you noticed that I have a - sign before the [expr ] ?

Didn't notice them, but I don't believe they should be there.
You're current expressions:
# Board trace delays
set max_btd 2
set min_btd 1
-[expr +$min_btd +
10 -$max_btd]
-[ 1 + 10 - 2 ]
-[ 11 - 2 ]
-[ 9 ]
-9
-[expr +$min_btd +
5 -$max_btd]
-[ 1 + 5 - 2 ]
-[ 6 - 2 ]
-[ 4 ]
-4
What the system view, source sync docs seem to be saying (no leading minus sign on the entire expression,instead tH value itself is negated):
[expr +$min_btd -
10 -$max_btd]
[ 1 - 10 - 2 ]
[ -9 - 2 ]
[ -11 ]
-11
[expr +$min_btd -
5 -$max_btd]
[ 1 - 5 - 2 ]
[ -4 - 2 ]
[ -6 ]
-6
The results do seem to work out differently. Tbh, I havent seen versions of these -max -min equations where the -min [expr... ] has started off with a negative sign.
