_aside:_ It's really confusing that there are e-mail thread and GitHub issues discussing the same thing. I keep seeing "Posting Dave Fleck's reply to GitHub" messages. It would be great if he would just comment here himself. ----- I didn't have anything to do with the current spec, but I suspect the motivation is that 1 is pressing really hard with a tablet, where .5 is closer to the amount of pressure someone would normally apply. If you change the default to 1, you're either going to end up with really thin lines when a pointer supports pressure or really thick lines when it doesn't. To test this hypothesis, I used my Wacom Intuos in Firefox and a Surface Book in Chrome. In both cases, normal strokes reported a pressure around .3-.5. 1 is pressing pretty hard. Thinking as engineers, it's tempting to make it binary: 1 is down and 0 is off. However, I suspect applications that actually care about pressure will work better with .5 - it's closer to the amount of pressure someone would probably be applying if the pointer reported it correctly. -- GitHub Notification of comment by appsforartists Please view or discuss this issue at https://github.com/w3c/pointerevents/issues/146#issuecomment-248724377 using your GitHub account
