I was calling him old before them to be fair, and I also said they were very good wins. Though Aldo has clearly lost a step and this factors in.

Holloway is obviously more skilled than Aldo having dominated him twice in a row,

Doesn't really work like that, styles make fights, Holloway is currently better than Aldo yes and his style matches very well with Aldo.

he also took McGregor to decision instead of getting KTFO.

The McGregor fight doesn't really tell us much about what Aldo-McG would look like if they fought again though. He got caught early, to me that means less than a full fight. Like with JDS and Cain, sometimes a quick KO is deceptive.

4-5 wins is absolutely ridiculous, 1-2 at most.

4-5 is not ridiculous at all, 4-5 is what it will take, at least. You are entitled to your opinion though, even though I obviously disagree.
