Trials displaying longer than their set time?

[amiefairs]

Thanks for clarifying the response received bit!
The actual length is 'recorded' by me counting out 'one mississippi, two mississippi', and I can do that for two mississippis on the words and three mississippis on the exclamation mark. Very scientific But then very obviously displayed for a long time, even though the csv output says they have been displayed for the correct amount of time coded.
I've only tried it on my laptop (a two year old top of the range dell inspiron) but with two different internet connections (one terrible, one mega fast), and the same problem happens with both.
