MegaSquirt installation timing?

In the next little while I'm going to be installing my MS2 (V3) as to Aaroncake's website.
On the page "Programming The ECU (MS2)":
http://www.aaroncake.net/rx-7/megasquirt/ProgramMS2.asp

He gives you a spark timing table to download (Under the heading "Basic Setup: Ignition Table 1").
Now I know that I can't say that that table will work perfect for my car without modification, but... My question here is, if my CAS happened to be adjusted a lot different than his was when he made the table, wouldn't my timing be off?
The thought occurred to me the other day when I was reading that section and I just wanted to know if I'm overlooking something.

Yes, If e CAS is incorrectly stabbed, the timing would be off.

Well I have the engine running great now with the stock ECU so I'm assuming it's stabbed properly, I was more referring to the external adjustment that you can do via the little bolt and turning the CAS the 20-30ish degrees. For example if his was adjusted far one direction, and mine was adjusted far the other way, the timing would be off I'm assuming.
I take it it would be the same case as you were saying, only on smaller scale.
So... to make sure it IS on, should I pull out a timing light and see or because it's not stock timing does the stock timing lines no longer apply?

Whenever you do a new install or adjust the CAS, you should use a timing light to verify the correct timing.

Just use the fixed timing setting and set it to -5, and then check the leading timing.
