The fact that it is possible to have more DoS than DoF does not balance- the current maximum DoF is 10 (target number 02 or less, to an absolute minimum % chance of zero, rolls 100), while the maximum DoS is >10 (such as target number 132 rolls an 01, where the top-end target numbers have no absolute limit...but the d% does). This is why d% game mechanics gradually break down- once target numbers exceed 100 the opposition must be on par or there is a distinct and pervasive lack of both balance in game play and Player challenge. The most effective ways to remedy this is with Characteristic caps of 70-75, possibly as high as 80, and by disregarding target numbers over 100.
I might just mention there was no real
need
to confuse the masses by changing the dice-reading convention a third time. However, I did so in my own games: DoS = tens digit + 1; DoF = 10 - tens digit. This promotes the concept of the target number actually being a "target", the center of the bull's eye (so to speak). It is also mnemonically superior to the latest official convention. A balance of 10 DoS/DoF.
In the event of a tie when comparing Opposed Tests, the highest d% result wins.
The only "break down" occurs with weapon Jam target numbers- a conciliatory hiccup that results from weapon rules, easily overlooked.
