Keep it simple- engine, wheels, bars
Can you please take some photos of the CNC part that mounts in front of the rear set. What is its purpose?

You do need to subtract the fork offset from that value. Dont forget that because the rake is hitting the floor at an angle the amount you subtract will be slightly bigger than the actual offset. Personally i think measuring trail in that fashion is a bit tedious when there are excellent trail calculators out there, not to say that you wont get good results with that. An added benefit of the calculator is you can change the values around to see what different mods will do to the trail. I use this calculator. http://rbracing-rsr.com/rakeandtrail.html
22 degrees on the headstock seems too steep. most superbikes are in the 23-25 degree range. btw I have on app called "Angle pro" on my phone that works great, you can just slap your phone against the fork and get a perfect measurement, no need to photograph.
another note on geometry; because you have increased your swingarm angle and have less fork offset your wheelbase has gotten smaller. Just something to consider when settling on final figures.
If you can, I would recommend adding some bracing to the headstock to deal with the increased forces it will be absorbing with the stiff forks and more extreme rake. it doesn't look like there are a ton of opportunities to add bracing with this type of frame but the pressed steel backbone needs all the help it can get in this department imho. heres a photo of my kz1000 head-stock i braced for the same reasons.
