It would be 190k. That's my point. If I change anything on the first segment they said even if I stayed on the second segment they will charge me more points. IOWs I cannot drop the first segment or change the first segment without the 2nd segment jumping from 62.5 to 190k as both people told me they can not retain the Mia to EZE in saver F as its no longer available and I will forfeit that. if I drop the first segment or try to change the first segment,

That seems unreasonable to me and I had I known this would happen I would have just booked MIA to EZE and figured a way to get down to MIA on my own.
