The thing about carrydown vs depletion is it depends on who your bowling and any pre-existing conditions etc.
Slowinski's article is based on what happened at Junior Gold and higher level bowlers all bowling similar lines.
League bowlers on the other hand can run into varying conditions.
Like players using plastic and urethane balls which can produce some carrydown. Now it will be said that any carrydown that may be produced in that way is meaningless to today's balls, that's true but depends on what type of ball your using.
If your using say urethane it can factor in and more urethane is being used today so is possible.
Also a lot league bowlers will be playing multiple lines, they won't necessarily be playing the same lines.
And if your on a league that follows another league and they only redress your lanes and don't clean them or don't clean them well. Then you can have dirty backends.
It's not that carry down doesn't exist, you got to recognize the difference between carrydown & depletion.

No, he doesn't say Carrydown never exists. Just that in a competitive setting, carrydown is not the reason for ball reaction woes. It is oil depletion that causes more issues for bowlers.

It depends on the situation. On my high end travel league I've never seen carry down everyone is using newer higher end balls and the lanes are freshly prepped. On my youth adult league that I bowl with my youngest daughter where half or more of the bowlers are throwing plastic or urethane balls on lanes that may or may not have been prepped since open bowling I've seen it a lot. On most leagues on freshly prepped lanes you are much more likely to be dealing with depletion than carry down.

A lot of it is the shear volume of oil. Most of the time we are dealing with house shots with a relatively light amount applied. It is rare that you see a house shot with a higher volume, believe me i hear guys cry the blues about my house being so slick. When you hear pedersen and others talk about it we have to remember they are dealing with those higher volumes. Again, those cases in our everyday bowling circumstances are rare compared to the other scenario but you will run into it.
