Protractor Screen

Today, in game, is Year 2, Day 127. The Alarm Clock mod says that the next launch window to Eve is on Day 139. Alexmoon’s Launch Window says Day 160.
With the errors I seem to be finding with the Alarm Clock and Launch Window Planner (designed for KSP1), I am going back to the old-school method of using a protractor and the Mark One Eyeball.
Except, I don’t want to just eyeball it. So, I drew some lines on a sheet protector that I can just hold up to my laptop screen. When things line up, it’s time to go.

And, according to the lines, the time to go to Eve is now. Twelve days before Alarm Clock predicts and 33 days before Launch Window Planner’s prediction.
We’ll see if this works.
Mission Designation : SCAN-14, SCAN-15
Rocket Model : EchoStar E-I
Total delta-V (to orbit) : 7,631 m/s (3,611 m/s)
Surface TWR : 1.297
Total Mass (to orbit) : 109.32 t (12.10 t)
Dry Mass : 21.32 t
Part Count : 22
Height : 31.24 t
Width : 6.32 t
Length : 6.32 t
Mission Objectives : Orbital Survey of Eve and Gilly
And once I get my craft built, in orbit, and eject from Kerbin orbit, I am on my way with a reasonable amount of delta-V expended. What I expected. I am going to have to keep testing Alarm Clock and the Launch Window Planner because there shouldn’t be any good reason for the math not to work.
