6, BI-6, and in my region it's signed as Ciclovia Adriatica 6. If you click on the relation link in your change set you'll see what I mean. Your 2 meter edit shows up for every along the adriatic coast, from Venezia to Brindisi, which it would not have if the relation was split up in segment and then combined in a super route. This single route relation is now in version 487 with 1993 parts. The SS16 is much worse, 4355 parts and version 1892.      Every meter added/subtracted adds a new version long as its a single route relation rather than split in subs per region or province. The Appennino Bike Tour I mapped over a year ago is at v30, the first 29 were for building all the stages, i.e. rarely highlighted as the members are a constant 44.
