I don't see why Gidley didn't just have a really quick attempt to be honest. In the 10 seconds or so it took him to explain they were declining the kick, he could have just whacked the ball on a tee and had a pot shot.
If it goes over, bonus, if not, well then clock still stopped very quickly so no harm done.
IMO this new rule about stopping the clock needs work. As the ref is not the judge of time then they also should not be the sole deciding factor in when it stops. I'd prefer the time keeper review the clock and if a few seconds is lost because a ref forgets to signal time off, or waits too long after a try is scored, then they add back on the missing time.
For the knights game yesterday the clock should not have advanced a single second from when the try was scored to when the ball was subsequently kicked off, as it was never in play and given the declining of the kick the clock should have been officially stopped the entire time. That actually would have given them an extra 10 seconds or so of time which would make the decision to decline more valuable as that gives an extra tackle on the ensuing set.
