Trivia #8 -- Busy-Bodies

This one concerns players and their workloads.
One point each for the first five questions,
two points each for #6-#8.

This is another trivia I'm giving not because it's
easy (although you *can* dig it out of the rankings
list easily enough) but for what it demonstrates
about the state of the game.

There is a clue, of sorts, the meaning of which you
must determine (but it may be easier to ignore it):

 1  2+3    4    8    6    7    5

Question 1: What was the greatest number of events
played by any Top 150 player?

Question 2: What was the greatest number of events
played by any Top 30 player?

Question 3: What was the greatest number of events
played by any Top 20 player?

Question 4: What was the greatest number of events
played by any Top 10 player?

Question 5: What was the SMALLEST number of events
played by any Top 100 player?

Question 6: For the Top 150, what was the MOST
POPULAR number of events to schedule? (That is,
look at the number of events each player played --
17, 20, 23, whatever. What number was played by
the most players)?

Question 7: A reasonable schedule is between 17
events (minimum for a full load) and 27. What
was the LEAST popular number of events in this
range?

Question 8: The top 150 played a combined 3568 events
in 2003 (or, rather, in the 52 weeks prior to November 11,
2003). Consider the number they played in 2002 also.
To the nearest four, how much did the total increase
or decrease from 2002 to 2003 (that is, if the figure
in 2002 had been 3560, you would say "increased by
eight"; had the 2002 figure been 3570, you would
say "decreased by two")?
