Hello all... it seems that "is the minimum" is not working as expected!
Take an expression pdif_4 running 4 mins before a race starts....on 5 runners
with S_1_pdif_4 = 0.25
with S_2_pdif_4 = 0.5
with S_3_pdif_4 = 0.6
with S_4_pdif_4 = -1.25
with S_5_pdif_4 = 0.15
"is the minimum" will choose S_5 instead of S_4 which is the minimum value!
