Has anyone completed this yet?
nope! i think the tables are pretty inaccurate from week 4 onwards.
after week 5, you take another test.. if you manage 45, you proceed to week 6. i got 41 on the test which means i redo week 5, doing column 3. i couldn't even finish the 3rd set it was that hard!

i decided to switch to column 2 in the end.
