Creating way points and then using the optimise (or optimize if you prefer) feature is awesome to gain the highest efficiency in your travels around New Eden.
When you have many way points, 72 for example.
Which then, before optimisation shows 289 jumps, hit that optimise button!
A word of caution. This message is not just CCP being funny, I left my computer all night working this out after I pressed "Yes", it still hadn't finished.
It also pretty much locks the machine up as it's thinking quite hard.
Eventually I gave the machine the three fingered salute and told it to reset.
You've been warned!
