Now 7/7 with Nanab Trick, 0/1 without Nanab
Caught my last one on the first throw too! I'm not here to boast. I just want to help some fellow homies turn their luck around.
Now this morning i got so excited after seeing an 1870 i forgot to use the trick and accidentally hit it with the golden first. And of course it had to fly away. fml

Perhaps OP will have a different description, but some in my raid group believe that alternating nanabs with goldens increases the catch rate. I tried it when I was 0 for 5 on Moltres, didn't help. Then today I got 3 out of 4, and a Lugia 1/1, without using it. So I think RNG but who knows for sure.
I just do the 1st throw as Nanab "in case" it's a thing...I doubt it works, but at the end of the day, 1 Nanab is a small cost just in case. With Niantic's code being so weird and last ball instant flee bug, I figure it's better safe than sorry.
I generally always hit greats/curves as well and in the 3 that got away without this, I got 23/25 hits without this trick and was 0/3 for 2 Articuno/1 Moltres.
I started to do the 1st Nanab on 2 Moltres and 2 Tyranitars and was 4/4 so far. That said, these last ones we got a lot of balls too so it could all be RNG, but I feel 1 Nanab is a low cost to pay to try it...
I'll keep using it since who knows, lots of bugs in the game.
