You have the calculations of the Hyuuga clan all wrong. The Hyuuga is broken up into only 2 branches to measure their potential strength. The main family and branch members. The main family were composed of heirs and was a relatively small family.
At best only the strongest of the HYuuga can stand up to a MS Uchiha. For the sake of the argument lets say their is max 3-4 Hyuuga who can stand up to one or 2 MS Uchiha. All 4 who know Rotation/64 palm and considered the best in their clan.
Now lets establish Manga Factual wise Chunin Neji is the about the average Hyuuga clan elite.

Now the Branch member family of the Hyuuga which is the majority of the clan is pretty much written off as above average fodder. Uchihas without sharigan wont go down without a fight because the majority learned to utilized ninjutsu, shuriken/kenjutsu and were part of Konohas police force.
At best they were only = to these type of Uchiha because Uchihas without sharigan weren't expanded and we've never seen Hyuugas outside the exceptional elite in action.
And Going by facts, we can now easily assume that 2t and 3t= HYuuga elite simply because chunin Sasuke 2t and 3t easily >= chunin Neji Hyuuga. And 1t Sarada average ninja > genin Hinata. Remember Neji also was a special case equivalent to Itachi.
The average are equal to the average Hyuuga. But the above average Uchihas are well above Hyuuga elite in the manga by overwhelming numbers.
So it goes something like this:
1 ems user is very rare, but destroys the clan so we'll him out.
1 MS user >= 4 Hyuuga main family elite
2 MS users = entire Hyuuga clan
4 MS users >>> Hyuuga clan
4 3 tomoe above average users = 4 Hyuuga elite
Out of the rest of the 96 members of the HYuuga lets say 20 are jounin.
3 tomoe = Hyuuga elite
That means 31 average 3t users should be enough to wipe out the rest of the 96 HYuuga members.
Lets say 20 were jounin 35 chunin and 41 genin.
The average members who contain only 1t or 2t tomoe sharigan Uchiha should be above your average Hyuuga, but cant take on multiple opponents. So those 20 jounin and a good percent of chunin are canceled out by 1-2t Sharigan Uchiha.
The average/fodder Uchiha member without sharigan should be about equal to a average/fodder Byakugan user using shuriken/ fireball jutsus.
