This article is quite clear that days to maturity is a very blunt tool. www.gardenfundamentals.com/days-to-maturity-what-does-it-mean/
Really what you need is then a conversion from a standard “recipe” into an “environment” that then determines actuation.
In your case, actuation is manual (pollinate), and the environment is uncontrolled, and not something you can control. We can however hopefully begin to develop predictive models (OpenAg started this with openag_sim that allow for us to plan ahead. This already has been going on for quite some time (crop insurance) but isn’t really accessible to the public so far as I’m aware. If we can plan ahead, and predict what the weather (PAR, Temp, Co2) will likely be, we can then communicate the proper GDD to the grower based on geographical location.
Perhaps an easier win, would be using logging (or real-time weather data) that is then localized to the user. If the user inputs the date they seeded, it could then tell them how many complete GDD’s have elapsed so far that season and what results they should be expecting.
Now we just need Burpee to fund someone to make this model for them and put QR codes on seed packs.
Cool ideas.
How would someone convert GDD back into Days-to-maturity?
Joseph Lofthouse, could not a simple Excel (or LibreOffice) Spreadsheet with calculations be doable for your growing season to tell you how many GDD are left (or actual days left) based on what the current day is?

what we need is a day where seed packets have both a crappy days-to-maturity estimate but also a GDD estimate as well. Wouldn’t take up much more space. I already like that Joseph includes "promiscuously pollinated" on some of his seed descriptions.
