In an official email form the Board applications processor I was told that I would receive my results 2-8 weeks after the 25 May board date.
In the past, from studying trends and other boards, results usually come out, on average, around 3 weeks later. This was compared to date from FY19 and 19.
Hope that helps. I'm sure if you're on a time crunch for orders/ PCS (mostly for prior service) an exception to release policy could be made if you contact the board directly or have your ECM contact the N31 department. Again mostly for prior service and you should do so at your own discretion, I'm not sure if it would affect your results to request them early.
Hopefully that helps.
