So the "Spratt" (God rest his soul) line might be changed to;

NEW: "Spratt guidelines of sniffer reporting 2500’ AGL to launch,
contestants/sniffer reporting 3300’ AGL to start, should be followed
unless there is a good reason for higher minimums."

This is not a rule, it's a guideline, and "unless there is a good
reason" is there for a reason! Yes, if you're in the boondocks, set a
higher limit. If you're in extremely hospitable farm country and have
a small number of gliders at the contest, lower limits are
appropriate.

The main point is, it is good practice to set some sort of
quantitative guidance for launch and task open in any given contest,
and at least consider it while making these tough decisions.
