Have my forks been dropped through the yolks?

[know your limitations]

I've been looking into various front and rear suspension options over the last couple of months and will ultimately be purchasing one of Devilsyam's R6 shocks when funds allow.
In the meantime, I want to take advantage of the cheap/free adjustments I can make to increase ride height and quality.
I've tinkered with preload, compression and damping settings front and rear and have been much happier with the new feel to the bike.

I've now ordered a 25mm jack up kit for the rear but have also read various posts on the forums relating to dropping the front forks 10mm or so through the yolks.
This pic shows how my forks have been since I purchased the bike but I have no reference to know what the fork height should look like as standard.
Have they already been dropped? If so, any guesses as to how much?
If they haven't.... where do I take the "drop by 10mm" measurement from?


Mine is a 2002 Gen1 1000


Experience tells me that this question will be bread and butter for some of you fine Foccers
