TPS over limit but still working without error

We have LTM 1600 with 1000 TPS license and recently we have seen in dashboard SSL TPS graph its reaching at 2000 to 3000 TLS/s but still i can access website and no TLS limit error in /var/log/ltm so i am surprised is this normal? i know TLS is count based on number of connection in 10ms window but still they are way higher, i am worried so thought if someone else has something to share
