On a recent trip across Australia with lots of fast and slow dirt roads (and some really gnarly sections) I am not aware of ever bottoming the forks but did use all of the suspension travel. Front and rear were set to 'max payload'; with no load this setting feels quite stiff.
I am no suspension guru so happy to defer to the experts, but my understanding was that if you are using all of your travel and not bottoming, you're pretty close to the mark. Of course, if all you are doing is riding on smooth roads than compliance may not be your primary concern, rather things like fork dive under braking, and you can get away with much stiffer and less compliant forks.
Well.. there's no way I'm ever going to be under 200 pounds (hell, i might go back to 280 if i leave the exercise/diet thing) and i do end up on the slab a lot (i still wouldn't call romanian roads smooth). Might as well accept it and prepare for it. Either way, slab or offroad, it's still underspung.
Now, I *might* have a way to send the forks to SPS without paying an obscene amount for shipping but it's not something definite so ... might as well learn as much as possible.
Thank you, Alex
