LAYOUT HELP AFTER FINDING THE BENCHMARK

Post by Clueless »

After you have determined your benchmark layout, how do you arrive at layouts such as control, long & strong, mid-lane, totally strong? The examples in Wiki - Dual Angle Ratio Guide uses 90* total sum.
I'm guessing that is just a random number to show how to do the math. The math I understand, how do you arrive at the total sum?
Specs:
Tilt = 27
Rot = 75
Speed = 18
Rev = 290
PAP = 5 over by 1 up

Thanks in advance for any info.

To determine the total sum, this is based on the speed to revolutions.
Matched speed to Revs is 95*. Adjusted up for rev dominance, low tilt or low rotation.
Adjusted down for speed dominance, high tilt or high rotation.
Libra, one of our members, compiled Mo's suggestions and came up with a spread sheet to get an initial total based on the speed to Rev relationship. I find it works well.

The basic range for totals is +/-20*
This is explained in the examples at the bottom of the Dual Angle Ratio Guide.

Thanks Eric:
Let me try to put this together.
According to Libra's spread sheet:
MPH - 18
REV - 290
Mo's Angle - 92 Benchmark Sum
Ratio Allocation according to tilt - 1:1.75 - 0.5 = 1:1.25
Angle Ratio = 1:1.25

92 divided by 2.25 = 40
92 - 40 = 52
40xx50 Benchmark

Find a long & strong layout from 92* total sum using a 1:1:25 ratio, you would add 20* and add 0.5 ratio.
92 + 20 = 112 total sum
112 divided by 1:1.75 ratio (has been adjusted with + 0.5)
1 + 1.75 = 2.75
112 divided by 2.75 = 40 Drill Angle
112 - 40 = 70 Val Angle

Any Thoughts

increasing the ratio would make the drill angle larger in comparison to the Val angle. decreasing the ratio makes the Val angle larger. In the example above, you decreased the ratio by makeing the Val angle larger.

You need to increase the drill angle to make the ratio larger (not the VAL angle),

Check out this example from your example I would have rounded to 90*
Rounding to the nearest 5* makes for easier math and 5* from the 95* starting point is an adjustment 3* from that starting point is not going to make much difference or within human error tolerance of the release.

Benchmark 90* total, 1:1.25 ratio .......40-4-50

add 20* to the Drilling angle of the Benchmark for the Long and strong...1.2:1 Ratio.............60-4-50

add 20* to the VAL angle of the benchmark Control................1:1.75 Ratio............40-4-70
