Lesson strength not updating on duome
It doesn't seem to matter how many times I practice the individual lessons they don't update on duome.
Travel 2 is shown as 50% and I've practiced this lesson dozens of times but it just stays at 50%.
I've logged out, cleared cookies and browsing data, logged back in, no change.
Does anyone have any thoughts on what might be causing this?
oh dear, so no solution to be expected soon (c) then! ;-p
Unless of course some kind soul at duome could issue an interim patch for these seemingly very concrete, language-pair übergreifende examples ... I’ll dream on :-)
Out of pure curiosity: Are the detailed causes known? Missing lexemes in the profile? Mismatches due to A/B trees? Cosmic rays?
Some while ago in a different thread, Thomas Heiss pointed out that "dead words" can occur, but I didn't know what he meant. However, I got the Basics1 and Basics2 skills in Italian stuck at 75% no matter how much I practiced them. When I looked at the Words list, I saw that a bunch of the words that I'd just practiced in those skills were still showing as Last Practiced "3 months ago" rather than "Just now". So the Duolingo spaced-repetition algorithm must be looking at that data and calculating a Strength that is less than 100%, as it sees that I haven't practiced those words for a while. Very sad, as I think spaced repetition is a fantastic feature to tell us what to practice and when.
I noticed for the first time today that one of my skills that is 75% strength (Basics 2) stays at the same percentage even after I did practice it from duome (10 times in row). Even a week ago, when i did not have this "issue", i did practice that unit once, so I do not know how it failed under 100%, and i practice all skills a lot and regularly. But, although I earlier noticed and read about irregularities in the word section so do not think it is very accurate, I do see that the words i had in the skill today are among "Last (just now) practiced" in the words section..
This is a very good observation! Perhaps, you can submit a bug report to Duolingo with your perception about this topic. I believe with have to create bug reports based on our experience when something obviously does not work. They may not know where to look in order to find the bug, but if we describe the symptoms to them they may be able to fix the problem quickly.
I have been trying to polish all my trees and bring the strength (Duome.eu) up to 100%, but I have recently noticed that the strength percentage is not updated for some of the units. For instance, I am currently learning Italian from French. I have less than 30 crowns left to finish the tree all the way up to level 5. As I was going along, I have also used the "revise" button on my cellphone and on the computer to bring all units up to 100%. But no matter how many times I try, Basic 1 and Basic 2 stubbornly stay at 75% and 50%.
I have a dim suspicion regarding a potential cause for this. I started revising Basic 1 and 2 directly from the tree first without using the revise button, but I used the revise button for all the other units. I simply kept using the Revise button and noticed that the percentages increased to 100% for all the other units. So now my tree keeps staying at 99% and I don't seem to have a way to change that. I have also noticed this type of behavior in some other language trees. I don't remember the language combination, but I remember that that Strength percentage did not even change when I tested units out from one crown level to the next. I used to keep all my trees at a 100% strength level before switching to another language combination, but that seems to be an elusive goal at the moment. Did anyone else noticed a similar pattern? Should I write a bug report based on my observations so far? I am not sure when this problem started to surface, but I used to have 28 golden trees at one point, but now I am down to 22. It's not really a crucial problem, but it would be nice keep the trees spotless again. For now, I will focus on collected as many crowns as I can. Shortly, I will start another language combination and keep my eyes.
