Ok much thanks. I am indeed keeping a notebook and I did do some slowing of rebound last time out to try to keep the squish in forks just a bit longer. I'll focus my attention on the shock next instead of adjusting the forks.
It's just my process, but after the physical components (spring rates, valving, oil weight, etc) comes setting the static and rider sag and the ride height. These are the cornerstones as changing physical components will pretty much universally affect the base sag levels. Once these are set, the forks should come next. My order of focus was always preload, then rebound and then compression damping. Once the forks are set up, I'd set up the rear in the same order with preload, rebound, compression.
Make literally one change at a time. If you add two click of rebound to the front, change the rear preload, drop the forks 5mm, etc, you'll end up in a complete bugger's muddle. You'll also very likely find that making an adjustment to one setting at one end will affect another setting at the other. Once you have your base settings, you can ride a couple of laps, making mental notes of the performance of the suspension (running wide, slow turn-in, twitchy on exit, etc).
Make notes of what your base settings are. If someone completely changed all your preload/rebound/compression, you should be able to set these to the correct bases within a couple of minutes. Once you've got your base settings, you can tweak things to match the circuit and conditions. If you have notes as to what you used before, you can set these in seconds, test them against any changes (to the bike or changed conditions) in a few laps and adjust them if necessary.
Afterward, while it still sits fresh in your memory, make a few notes about the settings you used on the day. If there was something that could well have been better if you'd had a chance to change it, record it.
Learning the feel of a change in your suspension settings takes experience to notice (unless it's really dramatic). The mechanics of suspension is one thing, but recognising the effects of those changes is probably more important.
Using a track day or two to focus on getting your suspension base setting just right pays serious dividends when it comes to going faster. It's not the rider who has the most powerful, lightest or stickiest tyred bike on the grid that usually wins. In my experience, it's most often the one that got their suspension setup just right.
