Steering effort while standing still or tight maneuvers

[Torqued]

This past week I test drove an Avanti I am interested in. The first thing I noticed was the high effort required during very low speed tight turns. It felt like almost zero assist in tight maneuvers. Like a manual steer car. Once you got rolling the car steered well. 

This cars past service history lists a p/s valve replacement. In searching the forum here, I see several discussions on p/s issues. I am trying to understand the nature of these cars. I have zero experience driving one until now. I have had GM cars of the 80's era, the same year as this Avanti. The p/s effort is minimal in the conditions described. Am I just accustomed to the GM level of assist?

How much effort does a proper functioning Avanti p/s system require in low to no motion conditions?
