Personally, I don't think "solving" minor inconsistency by eliminating a feature people like is the best approach. And from the way you talk about it, I gather you're not much of a Twitter user, so maybe you should give some deference to the people more familiar with the problem to decide whether this is a good choice or not?

If you have proof that other platforms have solved this problem at scale, I would be very interested to see it. Fundamentally, those totals are never going to be perfectly correct because a) people will be adding and removing tweets continuously, and b) even if continuously updating the numbers were worth the resources, people would hate having the numbers changing frequently.
