Yeah, at a glance doesn't seem too bad, would depend on how fast you can actually do one prefill+full decode run. Say you do it with 10 seconds per iteration/test, then it's only ~10 hours to verify next ten years. Definitely doable.
You wouldn't need to run all ten years ahead of time. Every Dec 31 you could test out the coming year, if you wanted to.
