I've been achieving 78-79% efficiency on my Mk1 Robobrew by making the following changes to my process:
* Change to a brew shop with a coarser grind - old shop was just pulverising it
* Using Bru'n Water spreadsheet and treating water with Calcium Chloride, Gypsum, Epsom and Citric Acid to hit flavour profile and pH. Note I'm not testing for pH but the numbers add up based on my tap water profile
* Consistently using 20L for mash volume (the coarser grind means that I don't need to use rice hulls anymore) and recirculating throughout the mash
* Yoga mat wrapped around the kettle to help with temp consistency
