Pretty much.
Pseudos are usually caught late and under-leveled. They have severely underpowered pre-evos, and they take a LONG time to evolve, usually with the base form evolving at Lv. 30, and then into the real deal at Lv. 55.
You're already essentially carrying a deadweight until Lv. 55. It doesn't need to take twice as much Exp to get there.
I'd make a case for an even worse group though...
Medium "Allegedly" Fast
https://bulbapedia.bulbagarden.net/wiki/Experience#Experience_at_each_level
It takes up to Level
68 for those mons to have less total Exp than the Medium Slow group (That's the starter group), and up to Level
45 before it takes them to need less Exp. per level up than Medium Slow.
Do you want to see an example of a Medium Fast mon?

IT TAKES ALMOST TWICE AS LONG FOR THIS LITTLE SHIT TO GET TO LEVEL 10 COMPARED TO A STARTER!!!
