Title: USBC Open Las Vegas, Interesting lane information
Post by: milorafferty on March 23, 2017, 01:42:30 PM
Looking at the website for the patterns for the previous tournaments and found this:


http://usbcongress.http.internapcdn.net/usbcongress/bowl/tournaments/pdfs/usbcopenchamp/2017/LaneMaintenance/2017SouthPointTopography.pdf




I'm not great at reading a lane pattern, but I can understand Topography.


This is the first year I have seen this available. Perhaps I just missed it previously.

Milo, I actually went and found this after you mentioned it. I love this!

Yea, I loved having it this year. And while we bowled in July and the maps were taken in February, it information was still accurate.

Well, I can't imagine the topography changing too much in 5 months.

I would assume that variances in temperature and humidity could have have an effect over time, but the changes should(and seemed to) be minimal for the duration of the tournament. Five years from now, the current topography maps might not apply to the conditions at Southpoint Plaza

I'd say it could change in a few months. Think about the number of bowlers, games, and surface being used along with bowler rev rate.

Saw an article once talking about the amount of damage these lanes take through the course of a tournament because of those reasons.

Lane damage from balls and topography are not the same thing. Temperature and humidity changes could cause the lane to warp, which would change the topography, but wear from balls traveling down the lane would not.

Does Typography account for lane surface/ware?

I would like to hear from somebody knowledgable on how can I interpret what I see on these topography graphs and make appropriate adjustments to my game?

For example, lanes 3 and 4 look somewhat different from each other.  So being a right hander how much of a difference should these two lanes play and what should I look out for what I should I do?

I won't describe what type of bowler I am because I'm comfortable adjusting speed and release/revs based on what I think I need to do.

Topography is how much difference in elevation and any changes across the surface. Not scratches.

The topography maps show how much an area tilts to the left or right. So for an area with tilt to the right(shades of blue), the ball will hook more easily for a left hand bowler, less for a right hand bowler.

How much more easily?  I see the different colors of triangles and their direction but what I'm asking is how much of a difference it really makes???  Does 2 blue triangles mean about 1 board more hook when the ball reaches pindeck and 4 black triangles mean 5 boards more?   

Can this be explained "bowling for dummies" style?  Today is the first time I've seen one of these charts.  Your help is appreciated, truly.

Ahhhhh ok. Thank you.

There was an article posted sometime in the last few years about the lanes after nationals and the affects the equipment plays in the ware of the lanes.

That would be great to see as a before and after each year.

How much would depend on bowler style(tilt, revs etc), amount of available friction(oil pattern) and ball speed.

Think  of topography as hills and valleys. If you are a right hander, the yellow, red and dark red are where your ball is going to roll down the hill toward the valley. If Blue to very dark blue, this is where your ball has to climb the hill out of the valley.

Areas of green are flat.

The maps are more of a built in tendency of the lane. But no matter the amount of oil, ball speed, rotation etc, a right hander will get a lot more hook when the ball hits the dark red area vs. the dark blue areas.

Exactly. A mountain will show up on a topographical map as a bump or high spot. If you build a house on the mountain and dig a swimming pool(akin to scratches from a bowling ball), the topography did not change as the mountain is still there.

A USBC Certs and Specs Story: Topography (2015 US Open)


ball motion topography Kegel Training Center
the slope on the lane 5 is .001 (flat) and the slope per board on lane 6 had slope per board of .004 to the right.
