No, please don't move anything - I posted at SETI Beta several hours ago, letting Josh know that much of this discussion would be visible to him even before he registered on this site (though of course he'll have access to much more once we have an account ID to upgrade).
Jason G:
LoL, OK fair enough. Next theories though lead to movie night at arecibo involving lots of microwaved popcorn.
Richard Haselgrove:
Get the popcorn ready - got another chunky indices.txt file to watch through - 1344 sample points..

If I didn't know any better (which I don't) I'd swear that pickup has a loose ground wire.

You might find it interesting to watch the changes in percent_blanked in the result file (it is rewritten with each checkpoint). The count of blanked samples should be limited to one DM, but it keeps on adding AFAICT. Because the count is kept in a signed integer, it can overflow into negative territory. The limits may be +/- 6400%, but if so I'm surprised we haven't seen larger values already. My current offline test on a slow system progressed from -38.121094 to -31.998047 in the last 40 minutes or so.
Edit: Aha! It doesn't really convert to percent, it simply divides the blanked sample count by the total sample count, so if they were equal the field would show 1.00000 rather than 100.0000 With that, the max range becomes +/-64. The name is wrong as well as the method.
