So when the streek is verical and you neutralize it with +4 , it means that you put +4 on the power cross at 90. Right?

Because we didn't use cyclopentolate drops..then no need to deduct. When we will instil the drops when we will deduct cyclopentolate value and working distance both.

Dear sir Should we not always consider the smaller value as the sphere ?? Means in hyperopic case you also picked smaller value as sphere n greater value as cyl , but in case of myopic example you used greater value as the sphere not the smaller (value)one
