It feels reasonable if you can tie the yearly values with events in the company. For example, MRK is going to lose their patent protection for Keytruda which makes up 40% of their revenue in 2028. Patent cliffs don't go to 0 instantly but some slowing down in revenue is expected. That would be an example of how you could explain adequately the variance per year. For KNSL, it could be an abnormally high hurricane season which decreases earnings in the future. All these things to say as long as the number is tied to the story of the company, I do not see anything wrong with varying values for each year.
Fellow coder here! I see you're making a DCF valuation. I also created one, but with VARIED values for each year - what do you think of such an idea?
