Burst-rate in show sipd stats

Hello all,

 

In "show sipd realms" i know that the value for burst-rate "high" is the highest inbound burst of simultaneous calls  coming in during this lifetime since reset / reboot
however, if i have enabled session-constraints and set "max-burst-rate" to 35 for instance….why can i then have a much higher value on the "high" ? would not the session-contraint have blocked that ?
