Generally, I like to stay in the background and read tips from other people, but being a semi-newly promoted level 36 who's played the game since launch, I've come to the conclusion that I should probably share my thoughts and personal research when it comes to certain things. Namely, raids.
I was away for an entire week, and when I came home, I wanted to get a Zapdos. I had heard from a friend that was in my raid group that if you use a Nanab Berry for your first throw and hit the Pokemon for the capture, then you have a higher chance at catching that Pokemon. So, I decided to use it on (almost) all of the raids I've done since this past Sunday, and here are the results, including previous results along with them.
FOR THOSE WHO DON'T KNOW, the trick is to use a Nanab Berry on the first throw, and, as long as you hit it, you have a higher chance at capturing the Raid Boss afterwards. For all of the raids listed below, I used Golden Razz immediately after the Nanab, except where noted.
After Nanab Trick: 7/10
Research Results: Inconclusive, but did start 6/6. IVs were good on all but one, and I caught that terrible one on the Nanab Berry.
After Nanab Trick: 1/3
Research Results: Low number of raids after trying the trick, but the one I caught afterwards has 100% IVs.
After Nanab Trick: 5/6
Research Results: Low number of raids after trying the trick, but only missed one.
After Nanab Trick: 0/2
Research Results: Only tried 2 raids. Can't gather anything from that. (I also missed on 3 of the throws prior to the last ball on the first one.)
After Nanab Trick: 1/1
Research Results: Only tried 1 raid. Can't gather any information from that, all though the IVs weren't great. I also used Pinap Berries on 3 of the throws after the Nanab, but couldn't catch it from them. I switched back to Golden Razz.
I also completed a Magikarp (for the candy) and Bayleef (for the raid at that gym for a chance at an Exclusive Raid), but only used Pinap berries on them.
Prior to Nanab Use: 23/48, or 47.917%
Using Nanab: 14/22, or 63.636%
While my numbers clearly show that I have a higher chance to catch a Raid Boss after using a Nanab Berry on the first throw, I must say that my results, at this point, are inconclusive. The reason for this is that if you take out the Moltres, my prior catch rate jumps up to 56.41%. While the catch rate is still higher, it's still pretty close. I'm going to continue doing the trick, if only for confirmation bias, but I would advise against telling people that his is a hard and fast thing at this point. We did see what happened with the OK Button, as that was debunked. However, I welcome everyone to do the same kind of research.
EDIT: I forgot to mention certain consistencies and controls that were put in place, as pointed out by Thorend (no ill will here; just wanted to point out that they're guiding me through). Here are what's in place:
- Every throw is a curveball.
- Every throw is a Great throw.
- With the exception of the Tyranitar, I immediately went to a Golden Razz directly after the Nanab.
EDIT 2: I shall update this list as I get more raids complete.
