This is how my association interprets this. I was taught that in a situation like this (where it is definately not zero or close to zero), briefly get together with your partner(s) if necessary and start asking yourself ... "Was it definately at least one second (yes); was it definately at least two seconds (yes) ... was it definatly at least five seconds (not sure) -- Subtract four seconds off the clock as you have definite knowledge that at least four seconds have elapsed.
