It´s literally impossible that you get anything better on day one due to lucky looter. There is no difference in loot between having lootstage 6 and lootstage 7. Take a look at the loot tables and you will see why lucky looter is a mid game perk.
At lootstage 50 is where it start´s to matter a bit, that´s when you can get a T3 AK47 with a lootstage of 55. Sure there is really small benefits below that, but do you really care about the tier on your padded cloth and stone tools instead of getting more magazines for your other skills? You would get that better quality stone axe a few ingame hours later anyways.
Like said, if you start in the wasteland with T3 POI´s it´s a different story. But doing that you need your points elsewhere to not die all the time.
And it doesn´t affect how many pipe guns or armor pieces your find. It only effects the lootstage and time you need to loot. Finding 4 pipe weapons on day one is purely RNG. I had that already aswell with no lucky looter. Pipe weapons do not spawn in T1 quality btw. T2 is the lowest quality that you can loot.
Nice map. Did you make that?
