Has optimum start adaptiveASHRAE been implemented?

I'm trying to put an optimum start schedule on my building. I noticed that adaptiveASHRAE is the default Control Algorithm for AvailabilityManager:OptimumStart so I ran with it. However I can't get the output:variable Availability Manager Optimum Start Time Before Occupancy to change.

After doing a little research I found that between EnergyPlus versions 8.8 and 8.9 a note was removed from the Input Output Reference saying, "The AdaptiveASHRAE algorithm has not been implemented yet." Implying to me that it has been implemented.

I dug into the SystemAvailabilityManager source code to try and figure out what why my model doesn't start before occupancy, and I found what I think is the relevant selection of code:

else if (SELECT_CASE_var == AdaptiveASHRAE) {
                AvailStatus = NoAction;}

The code implies with NoAction, that it still hasn't been implemented. I looked back to EnergyPlus version 8.2 and found the code above hasn't changed. Is there somewhere else in the code that I need to be looking to try and figure out why my model doesn't start? Has adaptiveASHRAE been implemented?

This is a great report and with investigation, thank you! When you are fairly certain you discovered a bug, you should post that directly to Github issues for the development to address.

I confirmed your belief, and opened issue #7089.

So bottom line: No, it still hasn't been implemented.
