I was just saying give the judges the option. If they are only comfortable making 10 different levels of difficulty among the spectrum of teams that inhabit each division, then they use tenths. If they find themselves wanting to have a more precise way to determine the World Champion between 2 super-elite teams, then they should have the option.
Again, there is no practical reason to force the rounding of scores. If a judge has given a team a .6 for Team A, a .7 for Team B - then decides that Team C is somewhere in between those two, they shouldn't be forced to tie them with a team that they feel is better/worse just because the guy typing in scores doesn't want to hit an extra key.
If the argument is that judges are only capable of fairly giving scores to tenths, then ALL scores should be rounded to tenths and ties given out if teams are closer than .05 apart in their final score.
Example: If 3 scientists disagree on the beginning of the Mesozoic Era - 2 think it was about 260 million years ago and another thinks that it was about 250 million years ago. You can't then definitively say the Mesozoic Era started exactly 256,666,666 years and 243 days and 8 hours ago. You don't gain that kind of precision among 3 estimates just by adding them together and taking the average.
Bottom line, let the judges use the numbers they feel comfortable with. If they want to just go with .7 - fine. If they want to go .725, no real reason not to let them.
