Engine rebuild tollerances

Rebuilding my engine at the moment. I would just like a second pair of eyes on the below list of crank measurements and clearances, specifically the rod journals.

How do you interpret the notation on the side as it's not like the mains?

Thank you! If anyone has more documentation on the F4R tollerances I'd greatly appreciate it.

Cheers, Graham

Don’t worry I sussed it. 48mm is the max with 0.02mm being the maximum permissible wear. Luckily all mine are spot on factory values. Everything is being measured, including the cam journals
