Yup, I always say 'about five' or whatever is on the watch.
What annoys me is when I am AR and players/coaches ask me 'How long lino?'
"Well, I make it xxxx minutes, but Ref's the timekeeper not me"
you can guarantee when MY estimate xxxx mins is up, they are at me again "Come on Lino, how much longer is he adding on???"
Had one a couple of week's ago, where, just as the ref has caught my eye and signalled '4' to me..... coach has said 'how long lino?'
"Minimum of four" I reply
"You never even looked at your watch, how can u be sure?"
lol...."I'm not the timekeeper, and the ref just told me!"
