Minimum load current of LM317 Resistor

Hello, I built the power supply from this topic. I build a version with 3 PNP transistors (TIP36C) with 1.2R Emitter resistors. I checked the behavior on the oscilloscope of the power supply at plugging and unplugging from the 230V mains. I have got good results. I checked the power supply by using an about 3A load at 25V output voltage.
If I will built a 10A version of this power supply (with more power transistors and a bigger transformer) then the behavior at plugging and unplugging with 9A load will remain the same as when the load was 3A ?
