Just as an aside, that is not necessarily how others would translate a 100-point transcript into a 4.0 GPA scale. The standard method is not to go GPA to GPA, but rather to first translate each individual grade into a 4.0 grade, and then average those.
So like normally, a 90 and a 98 would be translated into something like a 3.7 and a 4.0, then be averaged as a 3.85. But a 94 and a 94 might both be translated into a 4.0, and the average would be a 4.0. But an 89 and a 99 might be translated into a 3.3 and a 4.0, in which case the average would be a 3.65. And yet all of these would be a 94 average. Add more than two grades to the example, and a lot more possibilities fill out.
And yes, that makes no sense, because the 4.0 system makes no sense. And yet somehow it became the standard baseline system.
Anyway, the practical import of all this is you have to be careful making assumptions about how a selective college might view your transcript as a whole, and your GPA often does not contain anything close to all the information such a college might consider when evaluating your transcript. Which is among the many sources of uncertainty in US college admissions.
