I think that they were saying it was 6 degrees. I forget the specifics, but it was a VERY in depth article.
We had quite a few long discussions here about the articles & the merits of it. Subjects such as rev rate and other variables were tossed around here as well.
Here's a couple of the threads I've found here:

about what angle is needed for the perfect strike. I don't
remember the exact angle but the article said that when the
ball entered at this angle you would strike nearly 100% of
the time. It said that any variation, no matter how, small
would lower the percentage.

I think the ball has to hit the 1 pin first?
I am trying to draw a diagram for someone and show them what the perfect hit is.
As soon as I get this together, I will try to put it on a web page.

For a righty, ball path is 1-3-5-9..
Please check all the links given above by other posters. You could find pretty much useful information about what you are asking for..
Strike point is on 17th board (with a proper angle which is stated as 6 degrees. It is correct but I may add that this proper angle may vary between 4 to 7 degrees according to the lane condition, rev rate, speed, axis rotation and axis tilt of a bowler)
This 17th board is exactly 2 - 1/2 inches off the center of the head pin. Head pin is centered on 20th board and pin is 4 boards wide. Make your own calculation
Regards,
Burak

See this site and gives the postion and entry through the pins of the bowling ball. Must see.
Full site is http://mrcla.com/bowling/bowling-pres/
Then we have this.
Did you know there is a "Perfect Strike?" Studies done by the ABC proved there is such thing!
„X In a strike hit, especially a perfect strike, the ball only hits 4 pins - 1, 3, 5 and 9.
„X The ball must hit the head pin precisely at the center line of the 1, 2, 4, 7 pin row.
„X The ball must also strike the 3 pin precisely on the center of the row.
„X The ball then continues through the rack to hit the 5 pin at the center of the 5-8 combination.
„X The ball must then hit the 9 pin.
Notice that the Percentage of Strikes reaches 100% when the ball enters the pocket on the 17th or 18 board. That should be everyone's goal.

6 Degree Entry Angle Line: This line starts at the gutter at 45 feet 7 inch line to 2.5 inches right from the center of the head pin at 60 feet.
At 50 feet this line intersects just a little past the 5th board.
At 55 feet this line intersects just a little past the 11th board.
8 Degree Entry Angle Line: Line starts at the gutter at 49 feet 2.25 inch line.
At 50 feet this line intersects a little past the 1 board.
At 55 feet this line intersects a little past the 9th board.
4 Degree Entry Angle Line: Line starts at the gutter at 38 feet 2.75 inch line.
At 40 feet this line intersects a little past the 1 board.
At 45 feet this line intersects a little past the 5th board.
At 50 feet this line intersects a little past the 9th board.
At 55 feet this line intersects a little past the 13th board.
Just looking at this. The first question that came to mind was "Are the newer balls of today producing too high of entry angles?"
Now I know these are straight lines and a ball would move in an arching motion. Please someone correct me, I would assume that as the ball moves to the pocket after the break point the arching of the ball decreases as it would be losing energy when it hits dry.
