I don't know, I thought it was good advice. My trigger felt much better after running a lot of ammo through it. After 8,000+ rounds, I am not sure I would like a lighter trigger. Okay, I take that back, I don't want a lighter trigger. My trigger got nice and smooth fairly quickly. In contrast, an old revolver I have, one that had the action smoothed when I bought it, is now too smooth and light, and I have had a second round fire off due to recoil causing the trigger to be depressed a second time. That revolver has many, many thousands of round through it, and will be worked on soon.
So my advice would be the same, if the OP has not shot the gun much, I would shoot it a while before lightening the trigger. Then if the trigger still seems too heavy, modify it. Of course if the OP just wants to modify the gun, go for it.
