Approach in half orbit

add node(time:seconds + eta:apoapsis, 0, 0, 0).

lock rt to time:seconds + nextnode:eta + nextnode:orbit:period / 2.
lock dist to (positionat(ship, rt) - positionat(target, rt)):mag.

function increment  {parameter step. parameter type is "e".
if type = "e" set nextnode:eta to nextnode:eta + step.
if type = "p" set nextnode:prograde to nextnode:prograde + step.
if type = "n" set nextnode:normal to nextnode:normal + step.
if type = "ro" set nextnode:radialout to nextnode:radialout + step.
}
function adjust {
	parameter type is "e".
	set lastdist to dist. until lastdist < dist { set lastdist to dist.  increment(step, type). wait 0. print dist. }.
}
function tweak {
parameter type is "e".
adjust(type).
set step to -step/2.
adjust(type).
increment(-step, type).
print dist.
}
set step to 1.
tweak("p").
