With some logical powerscaling it should be around there yes, but the max we have actually seen was 114k in his fight with Meliodas who in turn had 142k and that was right before it was noon/The One. It was said by both Merlin and Melascula that Meliodas was back to how he was during the time he was the leader of the Ten Commandments as well so Escanor and Meliodas being far from their full potential just doesn't seem right.
I'm sure both of them will eventually have 200k+ powerlevels but that it's definitely not fluid progression.
They’ve said that about Meliodas about twice now though. And we know he’s still got some being revived left to do to his his true power. Iirc Meliodas was giving Escanor the business until closer to high noon, where he got stomped. If you take into consideration the difference in Escanors power when the fight begins, to when Escanor gets him, it’s reasonable that Escanor jumped up to around 200k at that point.
I can agree with it not being a very fluid progression, especially with people consistently saying Meliodas has returned/is returning, and then the manga saying he gets closer each time he’s revived. I personally think the next time he appears he’ll be back to his “true full power” Or even past that since it’s kinda confirmed he’s gonna learn/create his own special mov
The power levels I really wanna know are zeldrichs and merlin’s, her real one, cause her 44/4700? Is pure horseshit
