I reached 3e14 this morning, so I expect to get to 5e14 sometime on Tuesday, and I'll post then.

In the meanwhile, at 3e14, the smallest non-recorded gap is still 52048, and the next few also the same, 52102, 53836.

Largest gaps are now

180082 175934192636591
180083 246762443994551
180267 228767376933281
181948 228186907139291
188433 284010274084541
 195044 92944027480721

5e14 to 9e14 should be done tomorrow GMT morning so I will backup the data, will then run up to 17e4. Would be great to have a script to compare different gaplist.txt and create one with first occurrences. BTW, I have much more Largest gaps when I did trial the scripts last night on 50% of my range results.

I cannot test it right now, but you should be able to do this with "update_gap_list.pl" as well.

"update_gap_list.pl" will keep only the first occurrences. So, in principle you could use it to merge two gaplist files. Just rename one of them and treat it as a "logfile".

You're correct since both content are the same format, sorry. Will just post my gaplist file when I finish up to 9e14. Then Robert can update with his range.

5e14 to 9e14 is done.

Good to see some 200k gaps at last!

Silly me - I did not realise that "missing.txt" is a cumulative file. Hence I was reading the incorrect smallest non-recorded gap.

I'm now at 4e14. Still no 200k gaps, but the smallest non-recorded gaps are 88591, 88675 and 91673

Largest gaps at 4e14 are:

185573 387885927043031
186248 334473368863421
186438 369450712125191
187625 374568630680261
188433 284010274084541
189715 378576175419311
192024 376235797445111

Disregard the above, made a wrong estimate. I’ll make another reservation next Saturday.
