Here is a very rough order of magnitude estimation of the time required for
decoding. We selected 456 runs for the calibration timeline. Some of those
are special runs like luminosity scan or empty target, even a couple random
trigger runs. Nevertheless, I believe we have more than 400 production
runs. To process 400 runs in 40 days would demand decoding 10 runs a day.
This is about or more than twice what we achieved in the past when the
accelerator is running. One can also compare a rate of 10 runs a day with
the average number of runs we write on tape while taking data, keeping in
mind that writing data has a much higher priority than reading back.

At this point we should anticipate that we will decode and cook in
parallel. I am not certain how that interferes with the current plans to
write on tape. We need to make sure that we do not write decoded files and
reconstructed files on the same tapes.
