How often are you super lucky on one banner, but have horrid luck one the others?

I got nine Micaiahs from the last Radiant Dawn Banner...........I've been paying for it ever since.

This question is both lucks in one banner; the Legendary Banner from last month gave me enough Gunnthras to +10 merge, but the bad luck was that I was aiming mostly for Summer Xander and Performer Azura at the time.

I got two lyns and another sigurd from hero fest, then i get.no good fodder

I seem to be lucky with seasonal banners, but not so much for banners with focus units that get added to the summoning pool (Radiant Dawn, Sacred Memories etc..)

I have 0 luck in Legendary Banner, and try not to get baited into rolling to it (had been failed on the three banners lol)
First banner (with Fjorm): Only one Genny and BCaeda, Caeda's +spd-res
Second banner (with Gunthra): Only one BCharlotte
Third banner (with VIke): Siegbert (of all thing I just want another Sanaki)

Yep, 0 luck.

8% rate is a lie for me, I'm generally did well on other banner.

My bad luck was when Amelia first turned up on a banner, never got her. Merric and Titania pity broke me.

The other bad luck banner I had was with the first legendary banner. The hype of 8% was a lie, spent most of my orbs trying for Hector only to get Deirdre and S.Camilla with 200 orbs.

During Ayra-gate, got 2 of her durIng the same pull session both with good IVs. PA banner got Inigo and Shigure after 50 orbs.

Winter banner, got W.Tharja, W. Lissa and W.Chrom.

Managed to grab Myrrh a few weeks ago and recently with the LA banner got LA Hector, LA Roy and Sanaki in the same pull session with less than 30 orbs.

I usually have great luck on seasonal banners, average luck on new unit banners, and terrible luck on herofest/legendary banners. It's strange.

Random numbers are random.

I spent well over 150 orbs while sniping green on Hero Fest 3 before I pulled a B! Ike, but I had 3 LA! Hectors before I spent 100 orbs (also got a 4th 5* that I don't remember from the same circle as one of them).
