Rig tuning a 40' cutter

[rcassano]

The boat is a Baba 40:

The last time I had a professional rigger static tune the mast I asked if he was going to remove the Schaefer roller furling drum on both the jib and staysail in order to get the headstay and staysail stay adjusted. His answer was that they were fine and it was not necessary. My question is this:

1. How does he know they are fine when tuning the rig should start with loosening "all" the wires and starting from scratch?

2. Isn't the entire tuning process faulty if the head stay and staysail stay tension are ignored and not included in the "start from scratch" - "loosen everything" basic, Brion Toss rule for starting the rig tuning process? (as stated in the "Tuning Your Rig" video).

3. If the tension on the headstay is not sufficient would this put way too much tension of the forward lowers when the hydraulic back stay is pumped up to flatten the main?

As a boat owner and not a professional rigger I was wondering if maybe I was missing something here? In any case, I'm going to try to adjust and tune the rig myself to see if I can, at least, get things in the ball park. Any advice on the headstay/staysail stay tension would be much appreciated.
