[CQ-Contest] Use cut numbers judiciously

"OPERATING TIP

Don't go nuts with cut numbers and other time savers if they aren't
likely to be expected by the receiving station. Abbreviations only
work if everybody expects and understands them. So while 5NN is
universally understood as 599, using the sequence U E T for 250 is
much more likely to elicit a ? from the receiving station, wasting all
of the possible saved time and then some. Stick to the basics!"
