Suggestion for picking a weekly grooming crew

Assuming that we'll go back to Friday grooming in January, I have a suggestion for an equitable way to line up a crew each week:


All groomers will gain a "point" each week.

The people who groom on a particular Friday will have their point count reset.

The next week the people with the most points (the ones who haven't groomed on Friday the longest) will be first in line to groom. The ones who groomed the previous week will be at the end of the line (0 points).

People who want to groom will post a Comment saying so.

People who wish to take a bye can either Comment to that effect or simply not respond.

On Thursday night, the 4 people with the most points will make up the crew. People with equal points will rank according to when they responded.

It seems to me this approach gives everyone a chance to groom about as often as they desire. People who only want to groom infrequently will have a good chance of doing it on their schedule. People who want to groom all the time will have the best chance to do it without being a hog.
What do the rest of you think?
