when you plant tomato seeds that you know are three years old

when you plant tomato seeds that you know are three years old, and they germinate before all the other seeds you ordered.. make you wonder how old those seeds were. 100% of the tomato seeds I have on my shop are from 2023, what’s industry best practice just germ test and keep a secret seed lot number with them? that little green cluster at the back are sun sugar 2021, I’ve been saving seeds since 2015 for this variety as an amateur breeding effort, they’re fairly stable but I like to grow a few years to compare and just keep the best tasting and most true to type. In this case, an orange super flavourful cherry tomato.
