Hi --

Just now I pushed a new version of the spindown spreadsheet.

https://www.av8n.com/physics/spindown.gnumeric

https://www.av8n.com/physics/spindown.xls

The most interesting thing is a new diagram:

https://www.av8n.com/physics/img48/spindown-omega-z1.png

which is zoomed-enough to show the stair-steps associated

with the excessive and unreasonable roundoff error.

Also there are some lagged-residual plots, of which the

most interesting is:

In addition to the 20-per-second data analyzed previously, I

carried out the same sort of analysis for the 100-per-second

data. The diagrams for the latter are in the spreadsheet file

only; I didn't save them as separate .png files.

More finely-spaced t values are a step in the right direction,

but 100 per second does not solve the real problem. Not even

close. The important concept is, we don't necessarily need

more points; what we urgently need is two or three more orders

of magnitude more resolution on the timestamps on the points

we already have.

More resolution is synonymous with less roundoff error.
