This calculates the percentage that was lost and then the percentage needed to recoup the loss.

Starting Amount --> the bigger amount
Ending Amount --> the smaller amount

The Loss: Going from starting amount to ending amount is a xxxscore1=
(100*((Variable_1)-(Variable_2))/(Variable_1)).toFixed(1) percent loss.

Recouping the Loss: Getting back from ending amount to starting amount would require a xxxscore2=(-100*((Variable_2)-(Variable_1))/(Variable_2)).toFixed(1) percent gain.
