BLACK HOLE X-RAY BINARIES REGULARLY SHOW TRANSITIONS FROM A POWER LAW DOMINATED HARD STATE TO A BLACKBODY DOMINATED SOFT STATE AND BACK AGAIN. HOWEVER THESE TRANSITIONS DO NOT OCCUR AT THE SAME LUMINOSITY WITH THE HARD TO SOFT TRANSITION OCCURRING AT LUMINOSITIES THAT ARE A FACTOR OF FEW HIGHER THAN THE SOFT TO HARD STATE TRANSITION. RECENT HIGHER ORDER ANALYSIS OF BLACK HOLE X-RAY BINARIES OVER THE COURSE OF OUTBURSTS HAVE SHOWN SOME EVIDENCE THAT THE NON-LINEAR PROPERTIES DURING THESE TWO PHASES OF THE OUTBURST ARE DIFFERENT. WE PROPOSE TOO OBSERVATIONS CONSISTING OF 10 /NICER/ OBSERVATIONS OF 2.5KS EACH COVERING TWO DIFFERENT STAGES OF THE OUTBURST WHICH WILL PROVIDE VALUABLE INSIGHT INTO THE ORIGIN OF THIS HYSTERESIS.
