It is best to minimise guiding corrections where possible. Most guiding software does not cater well for large excursions, they take time and introduce errors and overshoots leading to the dreaded sawtooth.
The less corrections needed and the smaller they are then the target will stay where it's put in the FOV.
That is based on my experiences when the scope was 'close' but not close enough to SCP alignment. Since I did a proper alignment it settles within a couple of minutes and stays on target for the rest of the night. The steadier your scope is the better the image..
