The latest version of ZanRun now has a different way of ranking players globally, the initial points system was too strenuous on the server to calculate, and was causing lag spikes sometimes when people set personal bests or records. Now instead, players are ranked by their cumulative time, if they haven't completed a map, a high time value is added to your total time for each map you haven't competed, more detail from the github:
Working out each player's points every time someone sets a new PB turned
out to be too much work for the server. Instead people are now ranked
overall by their total (cumulative) time. If they haven't set a time on
all the maps, a high time (controlled by zr_maxtime in tics, e.g. 1050
which is 30 seconds for CTF) is set for each map a player has not
completed. zr_totalmaps must be set to the amount of maps on the server
so that this can be worked out properly. When transitioning from the old
points system version to this new cumulative time system, the admin must
puke script 469 to convert the database. If new maps are added, Zanrun
should add zr_maxtime*number of new maps to each player's total time
(assuming you also update zr_totalmaps), however you may want to puke
script 469 again just to be sure.
Fixed bug - players could teleport when dead causing voodoo dolls.
Fixed bug - personal TP binds now call the scripts as execute always to
allow people to teleport at the same time.
You can already see the changes reflected in the American ZanRun servers:

The Grandvoid web pages have not been updated to utilize the new ranking yet.
