Amount of fat in butter (cannabutter)

Yo, recently I made some (amnesia haze) hash yoghurt which had some pretty awesome results the first time.

I used some regular old butter a spoon and a lighter. I held the lighter under the spoon with the hash and butter until the hash melted. I've got some questions though.

First time I tried the hash yoghurt the high was perfect, it started slow after one hour but gradually got stronger and stronger, but in a way that definitely still felt good even though it was really strong at one point (was the first time I had edibles at all). I was extremely euphoric and everything my friends said made me laugh. Basically the best possible high you could have for a sativa strain.

The second time I tried it was about one week later, but it took me about two times the amount of hash to get as high as the first time and I waited twice as long (2 hours compared to 1) before noticing anything. The high felt like everything was just lagging behind 1 second and if I was a bit dizzy. It was overall good and I had a few good laughs, but still, I needed way more hash and it had a less positive effect and took waaay longer to work. Mabye I only got high this time because I made a second yoghurt and one hour after eating that I was pretty high. Who knows, maybe the first one didn't work at all.

(I didn't smoke anything or eat any edibles during the first and second time I had a hash yoghurt so my tolerance should have stayed the same). Maybe it was also because me and my friends just sat around this time and since the strain is mostly sativa maybe thats what made the high less enjoyable.

I wanted to ask if the amount of fat in the butter matters that much.I think this time around I used butter that had less fat in it (I didn't really look)
