50/25/25 (Butt/taper/tippet) is what I've done as a starting leader formula. I've always done the butt as two pieces, with the first (largest diameter) being 2/3s of the butt length and the second section being 1/3. I cap the jumps at .004, and prefer no more than .003.
However I also really like to keep the taper down to three sections. In looking at the the linked formulas, I would probably adjust them so that any of the shorter leaders had no more than three. The longer leaders, particularly the 15', or a leader that starts with a thick butt but also has to taper way down may dictate more than three taper sections. I usually have my three taper sections all the same length, more or less. with large flies, split, etc. some of the subtleties of these things go out the window. It's a little bigger deal when you're trying to tie up the perfect dry-fly leader for your 3-weight.
It is often suggested for "rocket taper" or maximum turnover to up you butt and shorten your taper. 70/10/20 gets thrown out there. I'm not sure you have to go quite that far, but 60/20/20 or 65/15/20 would work too. This might be a case where you do a third section in the butt or beginning of the taper that is shorter than the butt sections but longer than the taper sections. Again, length of leader could be a factor. Adding more sections to <9' leader would be vetoed by me, but if I was doing a 12'+, I'd probably do another section.
Not sure which line weights exactly you'll be tying for, but that is also an influence for me in starting butt diameter. Though admitedly I am also thinking of 3-7/8 wts, not 6-9/10 that I would think you'd be using for that list. But for 7/8, I just never found .024 useful.
