The Browser Width report brings data that are not as useful as it would be.
As we have multiple devices and screens accessing the site, the available width data ranges represent a very old market share. From 500px to 750px we have 50px ranges, but most of the browsers now uses wider screens. Most of the browsers are within the 1000 to 1499 pixels width. If we could break it in more ranges it would give quality data for redesigning. Like 1000 to 1099, 1100 to 1199, 1200 to 1299 and 1300 to 1499.
