This looks consistent. Here are some more grained summaries based on your filters:
=========================================================
| TO LEARN (%) |
===============================================================================
Proficiency | very easy | easy | reasonably easy | hard | very hard |
===============================================================================
no filter (any) | 4 | 20 | 55 | 19 | 2 |
――――――――――――――――――――――|―――――――――――|――――――|―――――――――――――――――|――――――|―――――――――――|
1. novice | 3 | 12 | 49 | 25 | 11 |
2. casual | 2 | 17 | 54 | 25 | 3 |
3. everyday use | 4 | 21 | 56 | 18 | 2 |
4. can offer advice | 4 | 23 | 56 | 17 | 1 |
5. know it very well | 11 | 20 | 54 | 14 | 1 |
=============================================================================== =========================================================
| TO USE (%) |
===============================================================================
Proficiency | very easy | easy | reasonably easy | hard | very hard |
===============================================================================
no filter (any) | 9 | 37 | 45 | 8 | 1 |
――――――――――――――――――――――|―――――――――――|――――――|―――――――――――――――――|――――――|―――――――――――|
1. novice | 5 | 17 | 47 | 25 | 7 |
2. casual | 5 | 27 | 51 | 15 | 2 |
3. everyday use | 8 | 36 | 47 | 8 | 1 |
4. can offer advice | 11 | 44 | 40 | 4 | 0 |
5. know it very well | 22 | 37 | 36 | 5 | 1 |
===============================================================================What appears here first is that the averages of the third category ("everyday day use") are _very_ near from the averages of the whole users. This gives a good confidence in the results.
Simplified summary:
===============================================
