I have recently been experimenting with different SS patterns with fb gut.
When I skip strings/intersections, it still notches the intersections without SS. I'm mostly going for string durability, and it seems like every intersection (in the sweetspot + some margin for error) might be the way to go. I didn't grow up using nat gut, so I don't mind the firm stringbed feeling. (It definitely feels different with 12x12 block of SS!)
I'm going to try Shroud's method with 12x12 section of my stringbed, using SS on every intersection.
Zoom in on Llodra's setup (he supposedly used fb gut), he has SS on most intersections of a 8x12 section:

Have you played enough with gut now to indentify a "break zone for you"? Here is what I mean: let's say you always break mains, and between cross 4 thru 6. If it was me, I wouldn't insert ss in the additional 9 crosses just for "feeling or consistency" reasons, particularly with fb gut. I think fb non-slippery gut or fb non-slippery multi are the best candidates for ss (just thinking logically ... have not used them myself other than chasing the frays, and now minimum location). So say fb bab vs or fb xcel. Soft ... not slippery ... doubt you need the full 12 rows for consistency/feel reasons. Also ... upside is less " (It definitely feels different with 12x12 block of SS!) ".
I feel different about using ss in fb velocity. I like the way v plays partly because it's slick. I absolutely would not step on that with rows of ss. I will add pics below on an example break, and current ss experiment. For 40 years I have broken 3rd or 4th main ... more toward tip generally.
I will post pics below.
Edit:
This was a good time to check my wear pattern (notches) at 9 hours. (so glad I am not a quick string breaker)
Blue - my hitting zone based on notches (I don't think I ever hit near throat or bottom edge, so the hitting zone is more narrow than the blue depending on which edge is up).
Red - seems to be my big notch zone ... hence the strange looking ss test below.
Interestingly ... even with only those 4 bab ss, I seem to feel the difference when I hit near them (maybe like a vibration, slightly stiffer). Probably in my head, but I look at that as a "teaching aid" ... "don't hit f***** up there".
Actually ... might be good to fill all of the 2nd, 3rd and 4th cross for that "teaching thing".
