Coaching questions...
What is Fred Borden's lifetime average? What was Borden's highest average ever? Could he average 200 on a typical house shot?
I really don't know, but this guy whom I bowl with has it set in his mind that the best coaches aren't always the best bowlers. We have seen 170-180 bowlers coach 160 bowlers into 210-220 bowlers. It has to do with observation and understanding of the game. A person who understands the fundamentals of bowling can probably coach anyone willing to listen to average 180+ on today's lanes. Add to that better equipment, and yes, that 180 bowler can easily become a 200+ bowler. Does that mean the 200+ bowler is now better prepared to coach than the person who only understands the fundamentals but has no interest in executing them on the lanes?
Yes, today's THS is much easier to hit than in years past. However, not everywhere employs a THS.
As for "out of bounds" (OoB)...
DPR, you made a horrible statement. It should have been, most everyone puts down almost no oil outside the five. After all, you need THREE STINKIN' UNITS on every board. And folks, that's nothing. For all intents and purposes, anything under five units is effectively dry.
Older centers (without newer machines/oils) still use wicking equipment. This essentially mandates that they do one of three things to remain within ABC specifications:
1) Don't oil.
2) Oil all boards evenly.
3) Oil more than once with two separate tanks and/or distances.
Here in Hawaii, I think all of the public access bowling centers use wicking machines of some sort. There are two bowling center that I know of that had non-wicking technology, but I believe both centers had their oiling machines "break" mysteriously. (I speculate that the employees are generally lazy and prefer using the Lane Walker -- the first generation -- to having to push and pull the Phoenix/Magnum machines.)
Because of this problem, most bowling centers choose option 3. Since many bowlers bowl between the 8 and 15 boards, there is a greater depletion of oil in that area (as opposed to the outer boards). If your morning run is 1-1 (across the entire lane) "flat" to 28 ft with a 45 ft buff, and your night run is 10-10 (middle half of the lane) "flat" to 20 ft with a 42 ft buff, you will probably have an OOB to some degree. (I am improperly assuming that the centers with older oiling technology probably have older ball return assemblies. I know this is not an accurate view, but it is this way at the center where I practice.)
Now, some will ask "why not oil longer with the 10-10 run?", well, that's actually simple to answer. If the 10-10 is longer than the 1-1, the lane will probably not pass inspection. After all, they measure the oil density based upon the distances used in the most recent oiling pattern run. Then again, since inspections seem to be non-existent, maybe they should just oil 80 units, 8-8, 38 ft.
Well, I'm not a lane maintenance person (and for good reason), so I can only speculate.
