Sony PS-X60 Overhang check

[Sandysound]

The rubber mat has the protractor on it which is pretty neat, so you just flip it over and hey presto!
The manual for the X-60 says to use the 235 marker, but this mat offers 237...

At 237 it looks like it's overhanging, but if I pull the mat 2mm further round, it looks bang on...
So... What do you think I should do?

I can't make the 237 mark work, the cartridge is as far back as it can possibly go which lines up with the specified stylus tip location for that headshell...

Think it's good as is?

The TT is all original, with a new (old) original shell, so it is as manufacturer intended.

Been a long time since I even had my mat off, so, I pulled it off just now. I have 235 and 216.5 scales on mine.
I'm not even sure if I've ever used them. It's been a long time since I've played with the turntable.
I'm the original owner so I know it's 'stock' and what came with the machine when new.
