That jetting chart is very conservative.
I run 52-55 depending on temps at 0-1000 ft.
At 4000 ft I run 52 and my needle at the second position.
I have ran this in my supermoto and my sand bike with no issues...
I think you need to lean your pilot a bit more but it is always safe to go a little at a time...
And yes... I'm open on Monday
