For F26,F27,F28 for the first 150 days of the year:

Days:  150
X86_32: 3769.4 avg/day
X86_64: 159540 avg/day
Ratio (32/64) 0.0236267 (1:42)

The reason is that the majority of i386 users are not moving off of
dead/old releases. For the month of May

Avg/day release
28623.7 epel6
16009.2 epel5
4043.37 f25
3318.53 f20
2759.2 f08
2127.8 f23
1589.63 f27
1401.7 f22
1371 f26
1277.53 f21
1056.33 f28
874.2 f24
733.8 f14
562.533 f19
509.067 f11

In comparison, x86_64 is mostly living on the latest release:
[smooge@data-analysis01 mirrors]$ grep '^2018-05-.* x86_64' out-2018
| awk '{print $3}' | sort | uniq -c | sort -bnr | head -n 15 | awk
'{print $1/30, $2}'
671455 epel7
605436 epel6
87367.4 f27
60159.7 f28
37857.6 epel5
34421.4 f26
27011 f25
19115.4 f23
14292.2 f24
8627.47 f22
6603.3 f20
5863.47 f21
1413.37 modular_f28
1091.87 f19
868.833 f18

The 30 is because only 30 days of May have been analyzed. [And yes
there are still many Fedora 08 systems showing up for x86_32]

Personally I think the number of those systems which are running
Pentium III hardware with the latest OS are probably already on this
mailing list.. I expect that they would also be looking at only
needing to support a small subset of the software since running
GNOME/KDE with usually 128->512 MB of RAM is not possible. It also
would probably want a very stripped down installer since anaconda is
aimed at 'current' hardware... probably something like the images that
ARM-32 makes.
