My run of chamber 15, completed in 20 seconds. This method includes the portal bumping manouvre. I believe it is very possible to get 19 as 2 areas of my run were done poorly (the portal through glass shot and shooting through portals).
If you would like to discuss anything related, add me on steam at darksim.
