In my own personal experience, I find that when upgrading within a week of a new version's release, the -latest files are not the current version. So if they release 2.4.3 on Monday, the earliest that the moodle-latest-24.zip file will reflect that is on the following Monday. I have not checked to see if the other files in the -latest reflect the current version or not. Considering the version number is wrong, I always assumed that the files were also from the previous release. In other words, if you're quick to jump on a new release in that first week, use the "latest official update" (2.4.3) not the "built every week with new fixes" (2.4.3+).
