The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About Performance Monitor

This extension was created mainly as practice for me working with Chrome extensions and its API. This extension can be used to monitor multiple system and tab-specific metrics including: CPU model, number of threads, memory capacity, screen resolution, CPU usage, CSS cache, image cache, JavaScript memory, network usage, script cache, and SQLite memory. It can be used during development to quickly monitor these things without having to access Chrome developer tools.
