I suggest that the strong disadvantage for the serving team in
doubles comes from the frequent pasa/corta whilst trying to get
around the front, at the same time trying not to give the back
a puffball. You're almost automatically in the 'neutral' state
if there's no over/under. The killer serve in singles would be
an easy grab for the front in doubles.
Much less over/under in singles unless you have a very agressive
server. A weak serve can leave the situation neutral at best,
while a strong serve can win the point outright or put the receiver
in such a hole that the result is almost a given.
Relating to the QOW, can we say (discounting pasa/corta and just
plain BAD serves) that most of the remaining advantage accruing
to the receiving team is the result of picked serves, the only
other way they can take control on first touch?
If so, can we we mine it from past history?
