BBV Please to be helping solve this staking arguement free 10$

[Eskaborr]

Staker A has already been staking a horse and the horse is now stuck 1400 in make up

Staker B wants to join in for 50/50 but both stake A and B want a fair way to deal with the make up before the stake goes to straight up 50/50

What is the fairest way for Staker A to get his make up And Staker B to be added into the staking agreement?

Best answer and reasons why will be judged by me and someone will get 10$, just so ppl will fkin respond with something other than "YOU ARE YOUNGHOV"....
