I have been testing with K6 recently and I have seen some output that caused me to question if it is valid
the output in full is below:

specifically the line that troubles me is the TLS handshaking line:
http_req_tls_handshaking.......: min=0s med=0s avg=142.76µs p(90)=0s p(95)=0s p(99)=0s max=5.16s
to me it does not seem right that the max is so high (5 sec), but the p99,p95 and p90 are all 0. With such high max’s I would have expected the p99 etc to be dragged up as well.
Can anyone help me make sense of this?
