Please explain how recombinator works in this case

Hello. I am following pohx's guide (https://pohx.net/crafts/) and have tried to recombine two weapons:
- magic weapon with a prefix
- magic weapon with a suffix

Into a rare prefix+suffix weapon, using Unpredictable recombination mode.

I've tried this 4 times, I think, but it always gives me one affix as a result. I've spent about 4k alts for this and starting to think that the recombinator is broken.

Here's a video: https://drive.google.com/file/d/1zlq0z0_4a76Jq01cD-3mEeKOvyFxAHsF/view?usp=sharing

4 times are not enough, it can happen. I also suggest, if it does not matter to your craft, to bentch craft some other mod in the wand to keep the cost low, and then remove them.By the way what chance does predictable give?

6.58% for 10k gold and 27k dust

Unpredictable says 100% for 12k gold and 25k dust.

Tried another recomb and failed again...

6% doesnt worth it.Personaly if it is 20% or higher I go with the predictable mode, unless I want to add a third mode down the road with recombinator. I don't know if the recombinator decides what to transfer by inheriting in some kind of way the weight of the affixes in the original items. But failing 10 times or even 15 times in a row is very, very common even when I try to recombine the most basic of modes into an item, like energy shield and increased % energy shield.
I know it feels hard, because it is, you are trying to recombine a mode that propably has 0,043 weight or something, that is hard to roll.
