I got 15 as a result, and I must say, that's a whole lot better than I would've imagined when I started this challenge. My main objective was to do a new personal all time record.
As far as I can remember my previous record before the challenge was 12 in my teens over 10 years ago.. so I accomplished my goal nicely.
Improvement has been so good that I won't stop here. I'll go back to week 5, column 2 this time. Still aiming for that 20.
