No, this is how Linux does the calculation. For FreeBSD, if a process is waiting or IO, it is sleeping and thus not runnable. Linux has the "iowait" ("w") state in addition to usr/sys/idle states and counts processes waiting for IO as runnable - which never made sense to me as it is counting apples as oranges. (yes, IO saturation is important for server status but it needs to be inspected separately - the LA number is too coarse for this).
