What's the shortest amount of time it has taken you to complete a language tree?
How much did you have to work on it each day?
Once I completed the English-German tree, two languages I am fluent in, in a few minutes. It was just for fun, and I have to say that I felt akward typing the German answers. They were all correct and good for learners, but not the way I would say it. I proposed some alternative answers, a few of which are now part of the tree.
Only completed Dutch, and it took around 38 days, but I wasn't rushing. I did around 150 xp/day, and it's hard to say, but it probably took about 1 hour a day or so.
About 20 minutes, Spanish tree for English Speakers. I tested out almost the whole tree, then I tested out one unit left. Other than that, I usually don't rush through the trees, it takes me months to complete them.
A week for Esperanto, I think I spent a couple of hours a day on it. I think it would be an interesting challenge to see if someone new to Esperanto could complete it in a day (without testing out), since the grammar is so simple and the vocabulary similar to English.
Well, I am not finding it simple. I have problems with memorization of words.
It seems it is gonna take me some time to complete the Esperanto tree. It is not as easy as I usually read. It could be it is just my case.
