Rev Rate.

[TotallyDefiant]

Well according to the graphs and charts on how to calculate your rev rate mine is 313 and I guess I am considered a tweener. It will be interesting to see what my rev rate is once I finally execute the release properly.

where did you find this graph and chart? i would love to find out what my rev rate is.

The chart gives an average RPM rate over the whole lane.

Consider that the RPM rate is changing all the way down the lane, as is the speed.

It's not a very good estimate of what RPM the bowler generates independent of other factors.

I prefer the video method

It measures the ball for just a short distance, before friction can change what the person does to the ball.

No way an expert at this, but logic tells me that revs should be counted for the entire surface you will be bowling on. This way you get a more accurate count, at least for that surface for that day, for that shot. Calculating rev rate for the first 20 feet gives you your rev rate for the first 20 feet. It doesn't give you your full rev rate for the entire shot. We bowl on a 60 foot lane bed. Not a 20 foot lane. When they oil the lanes for the entire 60 feet, then you should calculate for the whole time the ball is in the oil. I would do this a few times so you get an average.

In a car, your rpms are calculated on a constant basis.

The chart I found was in a video Bowl1820 posted. I can not remember if he posted it here or on BowlingIntel.

This is great information. My question would be this. If measuring before friction can take affect wouldn't it have to measure mine for atleast 44' since this is the distance of oil pattern my house puts out?

The THS is oiled around 40 feet, and only from 10 board to 10 board.

Bowlers most likely don't stay inside the 10 board for the whole 40 feet so for them the oil plays even shorter.

The whole point of measuring your rev rate, ball speed, tilt and rotation is to determine what energy you apply to the ball.

These values should be independent of lane conditions.

The only thing consistent about most lane conditions is the first 10 feet or so.

It's a fairly low friction area.

Makes sense. I have recently had to start playing more of the oil and not so much of outside of the 10 board. I am by no means in any situation to argue with anybody. Just a sponge at the moment absorbing all the information and knowledge that I can.

My house oils down to 44'. Rather long pattern from what I have observed about most TPS

Figuring your initial Rev's and speed in the first 15 feet is more accurate, than using the overall figures and is what is used when they are determining layouts and such.

But there is nothing wrong with using the overall rev's and speed to give you a general idea of your bowling spec's.

Yes that is from the powerhouse video "How to find a bowler_s PAP, ball speed, rev rate, axis rotation" it's posted here in the video section.

In it they tell you that the rev's and speed figured are just the average for whole lane.

What I love about my ball is there is not need for me to put the white tape on my ball in order to count the revolutions due to its color pattern. Typically what I am seeing correct me if I am wrong. But your rev rate in the first 15-20 feet seems to be higher than what it is for the full length of the lane. Is this correct or am I just way off base here?

While it is possible for the rev rate to be higher in the first 15-20 feet, I don't think it is a common thing to occur.

If you throw the ball at 18 MPH, your rev rate would have to be in excess of 700 RPM for the rev rate to be highest in the first 15-20 feet, than for the full length.

Again that assumes they haven't flooded the lanes the full 60 feet, gutter to gutter.

I'm gonna have to go to the lanes and try to figure all this out now lol. I've always been curious of what mine is just cause but never knew exactly how to determine what it is.

I did just that at practice today. Found the PAP on my ball and ran tape up to just above the finger holes. Found that my revolutions are right at 375 at 17 mph.
