Is there guidance in the handbook on such adjustments or did you hit on this by luck/trial/error/experience? As we are similarish weights, may well do the same on the RS when it a) arrives, and b) when I'm allowed out on it by Boris
Here's one on the new CB1100RS. For pure comedy gold, wait till 6m50s then listen to pained voice of the lad as an image he never wanted to see flashes into his mind!

.. would help if I included the link!
Experience really. I try to achieve a SAG of around 25%-30% of travel when sat on the bike fully clobbered up, that would be a generally accepted practice too. You have majority compression travel but also travel for depressions in the road. This is what preload adjustment is for, to take into account of differing weight loadings.
Having preload on the front is a bonus because it just gives us more adjustability and helps if you start to run out of rear adjustment. I could of used more rear preload and left the front stock but it leaves me no room to adjust for extra weight if I ever needed it. Many bikes only have rear preload of course but that is because most extra weight gets added at the back, e.g. pillion and luggage. My 2018 Triumph Tiger 1200 with semi active suspension has no front preload adjustment for example.
So now having said that is my goal, after adjustment, you then ride the bike. You should be just about there in terms of preload and handling because you used your own weight to get to this point. But If you find it a little reluctant to steer round corners it is still sitting too low at the back (or too high at the front). The reason it is reluctant to go round the bends is because the bike geometry is "raked out". You can then tweak the bikes attitude a bit more by raising the rear/lowering the front. This would only be a tweak though because you should of already got 90% of the way there with your initial SAG settings. If you find it too eager to drop into corners it could be because you are sitting too high at the back and you have made your rake too small.
Due to your weight being similar to mine you would want to add preload with a rear bias but how much I don't know because they are using different suspension on the RS. You could take a good educated guess that my settings would work out of the box for you too though. But do check it out for yourself because the RS has a sharper rake anyway. Regardless, you will still want to go up at the back though.
I recently revamped the forks and fitted a new rear shock on my Daytona, if you are bored out of your tree you could watch my two part video on suspension. Pt 1 being preload, part 2 damping. The part 1 is fine for the CB seeing as there is no damping adjustment. I warn you, I can be a bit long winded! https://youtu.be/hx6ExYqls9E
