I took about 3 months off lifting and my maxes seem to be 70ish lbs each below where they were. They were 455, 305, and 545. I wasn't sitting on my ass doing nothing. I was doing landscaping. I didn't lose much muscle, but did lose between 5-10lb and am a lot leaner in my waist.
Mostly, the weights just feel shaky and slow so I'm thinking it's mostly just a matter of honing in on my form and learning to be explosive again.
I get there's no universal answer, I was just wondering if people had any at least somewhat similar experiences they could share.
