HELP! The engineer I work with has some issues I am hoping someone can
enlighten me on.

Here is two calculations from Automata:
Automata's Lateral Crosstalk Modeling
You submitted the following name/value pairs:
Er = 4.3
h1 = 8
h2 = 8
t = 1 Oz
w = 6
sx = 6
length = 2
**** risetime = 1.9 ****
The crosstalk = 24.9 mv/v

You submitted the following name/value pairs:
Er = 4.3

h2 = 8
t = 1 Oz
w = 6
sx = 6
length = 2
**** risetime = 3.1 ****
The crosstalk = 31.9 mv/v

Does this seem correct to you?
Thanks in advance for any help.
