As a total beginner in tuning, I did my first pitch raise of our upright over the weekend -- on average about 25c flat, thanks to lack of tuning for some time and, well, winter -- and it came out extremely well, not through any skill of my own, but purely thanks to PS. I'll have to go back and touch it up, of course, and possibly do another small raise/leveling or two to get it to settle, but overall it was extremely interesting and rewarding to do it myself with app. (Vielen Dank, Frank!)
The question I have is around the settings for pitch raise, due to my lack of knowledge of piano construction.
This is a image of a model (Yamaha 450, maybe?) extremely close to my own, a 460C: 
"Highest Bass Bridge Note": based on the picture, is this the note directly to the left of the "V" with the medallion in the center? That is, this is the highest note with its pins still on the bass bridge and thus sounding "within" the bridge?
"Highest Wound String": unambiguous!
"First Treble Strut": the manual states "...the note that lies directly below the first plate strut in the treble." Does "below" here mean lower in pitch? My guess was "yes", going by the typical horizontal orientation of a grand. But "below" could also mean "closer to the floor" given the upright picture above. In other words, do I choose the note directly to the left (under pitch) of the strut or to the right (above pitch)?
"Second Treble Strut": My assumption here, too, was that this piano only has a single strut -- that one angled, raised bar approximately dividing in half the upper register -- so I left this as "None".
If I got any of these wrong, I doubt they impacted the tuning very much given my lack of skill, but I'd still like to do the right thing next time.
Thank you!
