CPF version numbers within the day

[daniel.d.dinu]

While browsing CPF data for ILRS satellites, I noticed that some satellites offer multiple CPF files for the same day of predictions. These are denoted with the 2 digit version number just before the data provider in the file name. What are the do these version numbers indicate exactly? More up to date predictions? More accurate or precise predictions?

The 2 digit version number is set to indicate the most recent predictions.
