650x23 wheel setting on polar S725?

The instructions give the settings for a 650x20 and the 700c settings but none for 650x23. Anyone know what it should be?

Jim I have the 720 Polar and a 650X23…my wheel setting is 1990.

Also you can measure the tire circumference and subtract 4mm (for the change after your weight presses down on the tire)

Thanks - I tried the measuring approach and came up with 1954. Maybe that is why my distance comes up shorter on the 650 bike compared to my Trek which is 700c and has the correct setting.
