Answer...

 This is mostly in response to the comment:
“You do realize that if you had this many pages finished you could have spread them out once a week for well over six months and used that time to work on the other stuff ? “

 

In order for me to maintain a constant upload schedule is to have at least:
2 pages/a week for the Library completed
1 page/week for the Archive
1 page/week for the Railroad
1 page/week for F-y-t

So that’s 5 pages/week without stopping.

Taking into account that I do need to prepare scenes/rooms, characters and write the story, oh… and let’s not forget the awesome “writer’s block”, where I stare at a blank page for days not knowing what to write, sometimes there are weeks where I don’t work on a comic at all. Pfff… I haven’t made a new page for F-y-T in 6 months, I haven’t even started writing the next chapter, and this was when the last chapter was completed by the old schedule (2 pages posted a week)  in around April, I think.

To avoid dead weeks I tried to complete pages ahead of schedule.

Minimum 3, ideally 4 pages/a week for the Library
2 pages/week for the Archive
2 pages/week for the Railroad
2 pages/week for F-y-T

So that’s 9 (10 ideally) pages a week.

I did try to work on only one comic at a time, that's why the Railroad's last chapter was already completed. But doing this cause all other comics to stop and wait until the current comic is completed.

 This would have worked if I were fast enough. 

Here are two tables I did a while ago with some estimates.

 

 The table shows if everything goes perfect and I can actually make 2 pages a week without interruptions.

The second table is if the Library is reduced to one page a week as well. As you can see, working on all comics there will be 30 dead weeks, and this is in the best case scenario so double that to 60 weeks (a year) of no posts for that comic.

Now I am not 100% sure I've done the math right so feel free to correct me if I'm wrong.

 

If I work on all comics during the week, I’ll have to change my mind set for each story, trying to remember, “wait… was supposed to happen here?” and this slows me down to about half a page a day for one comic.

I don’t have the time to work on all of these comics, I only have 2, maybe 3 hours a day when I’m dead tired to work on them. I’ve even stopped posting general drawings once a month in order to give some time to the comics.

The only idea that was perfect and was able to post pages constantly, was…
To post:
The Library - 2 pages/week (complete 3 pages/week)
The Railroad merged with F-y-T in a single story - 2 pages/week (completed 3 pages/week)

So that would have been a minimum of 4 pages/week or ideally of 6 pages a week. That I could have completed in a weekend.

But nobody liked the “merge” idea so I’m stuck with 3 comics instead of two.

Now, F-y-T and the Railroad are still merged and I still work on them as one comic but post them as two and depending on what happens in one comic it affects the other’s story. So I am taking into consideration to complete the chapters related to the story, so… actually expect to see a few more chapters from the Railroad before F-y-T.

This is why I prefer the priority idea. By posting one page a week that would have meant that a chapter would have taken more than a year to completely post, a chapter has about 60 pages.

Sooo…

In conclusion:

The only feasible idea for now is this “priority” method.

This way I can work on the Library and Archive relaxed. And I can keep the other comics separated.

Oh, and another positive side of posting by chapters RR and F-y-t is that you won’t have the unpleasant surprise of the comics stopping in the middle of the chapter for weeks until I get my poop together. XD

Hope that answers your question on why I decided to work this way.
