Here are some screenshots. It appears to be calculating the zoom for 100% incorrectly.

Lisboa correctly calculates 100% zoom as 1:378 and the current build incorrectly calculates 100% zoom as 1:267

• 5803 was configured as Lisboa.JPG
• 5804 was configured as Master.JPG

• Lisboa.JPG (Damien Smith) - Lisboa Correctly zooms to 1:378
• Master.JPG (Damien Smith) - Master incorrectly zooms to 1:267
