Title: Question for the lane graph savvy
Post by: bsone1 on March 13, 2012, 09:41:21 AM
Can a lane graph savvy person please explain to us (me) what is meant by the "ratio" of oil specifically in regards to the USBC Open? How is 25.2 mL of oil at a 2.20-1 ratio different than 27.35 mL at a 2.84-1 ratio?
thank you in advance.

In general, higher the ratio = easier the condition ... so 2.2-1 is tougher than 2.84-1.
Sport must be under 3-1. Blue patterns more like 4-1 and White more like 5-1. House shots get into the 10-1 or more ratio.

In addition to Riggs' good information, if you compare last year to this year, the 2012 pattern is 2 feet shorter, too, with less volume (25.2ml).
My house shot this year is 9:1 so that means there is a huge amount of oil (comparatively) in the middle portion of the lane compared to the outside (1st arrow area). The THS patterns give you hold area if you miss inside, and bump area when you miss outside.
The flat ratios make accuracy and repeating shots extremely important or you'll pay the price. If you have a chance to watch any of the live streams of bowlers at Baton Rouge you will notice how "touchy" the shot acts when the bowler misses inside, due to lack of hold area. The "fluffed" shots that swing too far wide tend to come up light or miss the head pin entirely. Hope this helps.

Can someone also comment on the effect of "reverse oil"? Last year to this year it doesn't appear to be that much of a difference other than there being some reverse on the outside this year (and thus a little more volume), but I've noticed that some patterns have as much reverse oil as they do forward and I'm curious to hear what the effect of it is.

So if I understand correctly, it is basically the ratio of oil from the middle portion of the lane to the outside portion of the lane?

Yes

If I am not mistaken, reverse oil gives you the "hold area". The forward oil creates the general shape of the pattern, but lots of reverse helps the pattern hold together longer. Less reverse will do the opposite.
The house pattern we use (see above post) is also 19 ml of oil. The USBC Open uses 25 ml of oil as a comparison.
This years' pattern at Baton Rouge will test the shot making abilities of the bowlers without being "impossible".

Bsone1, this is all good and correct info you are receiving on here. If you want to educate yourself further, read a few of these articles:
There used to be a few really good articles on this topic, but I think they got deleted sadly. But tons of great info given on many other things.

Basically, forward oil gradually fades out, when the oil machine moves towards the pins. It creates a transition zone between the "full" oil and the dry lane areas. Reverse oil is applied when the machine comes towards the approach - and it creates a more defined "end" of the application area.
The actual effect must be seen in the combination of both methods, though. But if you have an area that ends in reversed oil, you can expect (recognizable) less room for error and probably over/under issues, because the wet/dry contrast is much harsher than on a buffed forward oiled area, where friction rises gradually. Combined with a relatively flat sport pattern, breakpoint errors are magnified, so spraying will be punished a bit more than just through the flat pattern that offers no (or little) bumper area.

I believe it's the ratio of oil for the board with the MOST amount of oil in relationship to the board with the LEAST amount of oil applied while in the forward oiling mode. The finished product may be slightly different due to buffing or reverse oiling/buffing. I'm sure someone will correct me if I'm wrong. The 25.2 is the total volume of oil placed on each lane.

It's also flat from 13-13 I believe. So no ratio there. The little taper that there is will be found outside 2nd arrow. And from what I've heard and seen, that sounds about right as far as where people are having some success.
