Why can’t ALL actuarial early retirement pension factors be calculated accurately instead of only discrete accurate factors being tabulated with ‘in-between’ ones being interpolated?

Because accuracy is meaningless in this context.

Is this really different from the question you asked here?

[Table based calculations of actuarial present values - Factual Questions - Straight Dope Message Board](https://boards.straightdope.com/t/table-based-calculations-of-actuarial-present-values/1008222/10)

Or on Quora?  
[Why can’t actuarial qx and lx tables be produced showing accurate qx and lx values for x in months rather than just for x in years? - Quora](https://www.quora.com/Why-cant-actuarial-qx-and-lx-tables-be-produced-showing-accurate-qx-and-lx-values-for-x-in-months-rather-than-just-for-x-in-years)

I also see you’ve started 15 or so threads on mortality curves on a site called the “Actuarial Outpost”, would that be a better reference than the SDMB? I assume there are practicing actuarials there.

You’ve also been posting about mortality curves (or someone with your name and interests) on a place called “GoActuary”, which sounds like a command to depart, or an energetic encouragement.

Just trying to help you get to a satisfactory answer here.
