What are the "payoff" times for EvE learning skills? [closed]

Solution 1:

Learning skills were entirely removed from the game in mid-December 2010. Any points invested in learning skills were reimbursed. Players can instantly apply these points to any other skill they like.

Skill books are no longer available on the market, and any skill books sitting around in containers were reimbursed at the NPC selling price.

All new and existing characters have an extra 12 points in each attribute, to make up for the skills' removal.

The developers have a more extensive post about the change over on the EVE Dev Blog.

Solution 2:

You probably don't really want to see a chart. It's a lot easier if you use EVEMon. It automatically looks at your queue and suggests learning skills that would make the training go faster than not learning them. If you keep using it, you'll automatically build up all the training skills you could ever need.

Learning skills were removed. There is no pay-off for something that doesn't exist.

Solution 3:

I found a fairly good overview on the EvE wiki, here. However, it is marked as potentially inaccurate due to changes that have been made in expansions/updates.

It also includes this provocative note:

"It is important to note that this is not a typical method and that a spreadsheet was used to calculate the absolute least amount of time. EVEMon does not give the best possible time either."
