Does Typography account for lane surface/ware?
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 and the chart explaining what each color/direction means 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.
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.
