Maybe the standard shouldn't change, but I think that in practice, it inevitably will change.

Consider a ILCA national championships.  Mid fleet, while not showing the superb boat handling of Robert Sheidt, or Brett Beyer, boats will consistently be making tactical crosses inside significantly less than half a metre, and reasonable apprehension will tend towards that level of skill.

Now think about a bunch of sailing school Fevas, and reasonable apprehension will be considerably broader.

 The reasonableness test, at the end of the day, however we moderate and qualify it, depends on the judgement and opinions of the protest committee.

As Michael Butterfield said

Experienced judges will be able to 'dial down' the skill level they consider reasonable.

A holywood is really a match racing term for a great show, but may not be genuine.

@Lars - having done a number of WASZP events, I found the RRS 42 rules easy to see and enforce.

The world sailing judges manual changes on improper act or ommission in each version, each seeming giving judges more room for interpretation. Just track the change next time, it may be what gordon and i may expect.
The old bad race management hidden behind the word may not shall,, may not be tolerated.
A time of change perhaps! I believe for the better if we are to improve standards and improve the sport.

To me once a boat had done a 44.2 set of turns, they have not initially finished and there can be no other score but the last finish.

Other rule breaches are something else which really should be protested by boats.

There is no reason for a rc to act if they score the finish after the turns.
