Support for Apple Health daily weight average

I weigh myself twice a day, morning and night. Apple Health averages these two weights and displays the average as my weight for that day. I’d like regimen to do the same

Regimen does not seem to pull the average, and I cannot discern any pattern to how it picks which weigh-in to import from Apple Health on day when there is more than weigh-in. Can you provide any guidance on this?
