Here is a simple, closed triangle boundary you can test right now. This is specifically designed so you can intuitively verify the math in your head.
You can paste this exact block into the Bulk Import text area:
Plaintext
PEG_1 1000.000 5000.000 10.000
PEG_2 1100.000 5000.000 12.000
PEG_3 1100.000 5100.000 10.000
Here is what the calculator is going to do when you hit calculate with all 3 pegs selected:
Leg 1 (PEG_1 ➔ PEG_2): This moves 100m straight East and rises 2m.
Bearing: 90°00'00"
Horizontal Distance: 100.000m
Grade: +2.00% (or a 1:50 Ratio).
Leg 2 (PEG_2 ➔ PEG_3): This moves 100m straight North and drops 2m.
Bearing: 0°00'00"
Horizontal Distance: 100.000m
Grade: -2.00% (or a 1:50 Ratio).
Leg 3 (PEG_3 ➔ PEG_1): The closing leg forming the hypotenuse. It travels South-West back to the start.
Bearing: 225°00'00"
Horizontal Distance: 141.421m
Grade: Flat (0.00%).
