On top of that I'll bet (and I have nothing to back this up) the drop out
rate for pilots that spread training over a long period of time is probably
higher. And God knows we hate to loose somebody that wants to fly
bad enough to start the process.

Our flight school encouraged people to fly often/consistently and
complete their goal(s), and counseled people who spread flights
apart by more than a week -- aside from skill/proficiency, many
CFIs don't stay at these schools more than a few months (they
build the hours they need and then they're gone). But few such
endeavors have a 100% completion rate, and dropouts are not
always a failure on anyone's part. Sometimes as the training
progresses, it just becomes clear that it's going to take more time,
dedication and money than the person initially thought, and he/she
realizes it isn't something they want or need that bad or is cut out
to
do. Sometimes it's a common sense, realistic, prudent decision.
