I can't say for sure. It is unlikely for us to combine 2 file histories
into one group if it is larger than 4MB. The current logic should be:

a) If the current group has all the same file, it is allowed to grow to
   2x the size of the largest content or 4MB, whichever is larger.
b) If a group has mixed content, it is capped at 2MB

So if you have 10,000 revisions of a 1KB file (with no delta
compression), it should pack into 3 groups (4MB, 4MB, 2MB).

If you have 10 files that are all 1MB (no delta compression) it will be
in 5 groups (2MB, ...)

If you have 3 versions of an ISO and get some delta compression, it
should end up in a very large group (700MB base, + <700MB of deltas).

Now it is possible that the "419" includes the compressed and
uncompressed sizes. Though that is still only 240MB...
