missing last point on chart

[dfarrow0]

A fresh instance of epicast, which I assume is how the site appears to new users in production, is missing the very last (right-most) point in the black prediction curve. Unless the user specifically extends the line, this causes predictions to be too short by one point. And unfortunately, such predictions having unexpected length are dropped when generating the weekly epicast forecast.

This is likely related to the week 40/41 fix from last week that never saw testing... I should also should turn that silent drop into a noisy one.
