You say that the ANT_WIN_VS_NOWIN contrast corresponds to Win ($1 and $5) vs No Win ($0). However ANT_WIN_VS_NOWIN seems to be defined as a simple contrast of 'WANT -W0ANT', suggesting WANT is itself Win ($1 and $5), and No Win $0 is -W0ANT (that part seems reasonble).
Would you be able to clarify 'Win' more? Exactly what is Win $1? What is Win $5?
