earlier today I spoke with tech Dave Durbin, of yamaha Corp. He confirmed that the stamped scale indications on the long bridge are INDEED Metric, as I suspected. On the vast majority of grands, and probaly uprights as well, "Suzuki" wire, which is metric sized, is used. Bottom line from Yamaha: When restringing with American Standard wire, use 1/2 size smaller than indicated on the bridge. Simple enough.

On Terry's piano the last size stamped on the bridge is 13.5. This is several unisons towards the bass from note #88. In other words there is no 13 stamped on the bridge! The size from #88 note down (towards the bass) to the 13.5 stamp is size 13 wire. From 13.5 stamp down (towards the bass) to 14 stamp is 13.5 and onward.
