Talent and affinity for Nen categories are not necessarily related to each other. Talent can be taken to mean that Gon will be able to reach very high Levels very quickly. Furthermore, we cannot take the abilities of other Nen users to prove anything. Biscuit's masseuse may be an ability that only requires, say, Level 5 skills in Transmutation, but Biscuit may be a Level 40 Transmuter and use Level 18 Manipulation in that ability.

The difference between Levels and Force/Accuracy is supported by chapter 108. Unless both the unofficial translations and Viz made a mistake, that is just how it is, although it can be controversial.

But if we really want to look at an example, take Gon's Jajanken, for which we know exactly how much aura is consumed and to how much aura the output corresponds: according to Knuckle, Rock costs 2000 aura, and that is also its output (efficiency, 100%). However, Paper, despite still consmuing 2000 aura, has the force only of a 500 aura attack. If it were only a matter of affinity, Gon should have 80% affinity for Emission (possibly even more, according to Biscuit), and Paper should be as powerful as a 1600 aura attack; however, that is not the case.

However, all this example really shows is that we can't use abilities from the manga to determine a characters' Levels, Force/Accuracy etc.: despite knowing how much aura Gon expends and the corresponding output, we don't know if Gon had maximized Emission.
