I disagree! We agreed that the value "is similar to the uptime" command.
Load values indeed can be bigger than 1 because they measure
the amount of "runnable" processes in average. There is no need to
artificially normalize the value somehow because the max. number is
unknown. We should take whatever the DRM is reporting us, and this
is similar to the uptime command (and by the way also depends on the
amount of cores). This is we agreed on.
