I ended up removing a chrome extension that randomises user-agents because of this. It dramatically cut down google captchas. Another thing that sets it off is virtual machine usage, I can be logged into chrome and gmail on the same residential IP for hours but the moment I try to search google for a problem inside a VM it's a minute of slow loading captchas. Have moved to bing instead, that sort of wasted productivity is a burden.
