pigtailed wires downstream of a gfci
If I understand your question correctly, the answer is it is irrelevant how you connect the standard receptacles past the GFCI one. What determines whether they are GFCI protected is how you connect the GFCI receptacle.

If you connect the GFCI receptacle to the line connection only (usually using pigtails) and do not use the load connections, then none of the following receptacles will be GFCI protected.

But if you feed the following receptacles from the load connections of the GFCI receptacle, all following receptacles will be GFCI protected no matter how they are connected, i.e., with pigtails or by using the receptacle contacts to feed the receptacles further on.
