If the user knows that round trip delays above a certain level should cause the If the user knows that round trip delays above a certain level should cause the
measurement to be ignored, this level can be defined with the *maxdelay* measurement to be ignored, this level can be defined with the *maxdelay*
option. For example, *maxdelay 0.3* would indicate that measurements with a option. For example, *maxdelay 0.3* would indicate that measurements with a
round-trip delay of 0.3 seconds or more should be ignored. The default value is round-trip delay greater than 0.3 seconds should be ignored. The default value
