This is a pretty interesting battle report. I feel like people like to talk a lot about points efficiency, but this report really highlights turn efficiency. The land raider and centurions were in a horrible position and weren't really proactive in trying to change that. The fliers also bled turns in reserve then positioning and from having to jink. Was he thinking defensively - hoping his fliers could change the tide in later turns?
It seems like he was overly passive initially and you were able to capitalise on that - nice win!
