Finished at full runtime - 7 single pulses and 30 repetitive pulses. Result file attached - full WU datapak available if you want it uploading.

Try to do the same WU with 4.x version, then send both result files along with indices.txt, stderr.txt and WU itself to FTP, please.

What's the best way to get a v4 result offline to compare?

Think opt app will be fine. No need to use 4.x stock one.

Got some more completed work units on Cruiser:
Main:368768645 (Pending), 368768653 (Validated)
Beta: 1563494 (Validated)
Cruiser's compiled results so far:
Main:
368768645 (Pending) - 0.008021076 credits per CPU second
368768653 (Validated) - 0.008183099 credits per CPU second
368496971 (Pending) - 0.008235288 credits per CPU second
368418713 (v4.37, Pending) - 0.006726898 credits per CPU second
Beta:
1563494 (Validated) - 0.009484371 credits per CPU second
1565756 (Validated) - 0.009705443 credits per CPU second
1564992 (Validated) - 0.009227865 credits per CPU second
Fairly consistent on both Main and Beta...
For comparison:
Shorty Multibeam (16.84 credits): 0.007037046 credits per CPU second
Average Multibeam (44.12 credits): 0.008375063 credits per CPU second
Long Multibeam (63.86 credits): 0.010619245 credits per CPU second
Raistmer:
Again, rep pulses overflow....
single pulses: 8
repetitive pulses: 30
single pulses: 12
repetitive pulses: 30
single pulses: 7
repetitive pulses: 30
All main ended with rep overflow but no such effect on beta. It seems tape w/o radar used on beta .

About a week ago I went through Richard's Beta reports from opt 5.00. There were 26 of them, 1 was a 30+30 overflow, 3 more had 30 repetitive pulses, 4 had no reportable pulses of either type. In total, there were 108 single pulses reported and 179 repetitive pulses. That's a very small sample, but at least indicates the "tape" covers a wide range of conditions.
The "radar removal" is looking for a DC level from the length 1024 FFTs it uses, which I think is an effect of getting a strong enough input to saturate the receiver channel, or at least cause compression. Assuming those incidents are caused by radar signals bouncing back from an airplane, the strongest ones are going to be when the bounce arrives on one of the side-lobe peaks and/or when the aircraft is oriented to produce the strongest reflection. It's a hugely complicated set of interactions.
