I really hope that's the case, but it's a lot of chapters for 26 episodes and it will be a stark contrast to S1's pacing.
The Stain arc is way too short to drag that on for a prolonged number of episodes. It's 10 chapters essentially so if we use S1 pacing that would roughly 6-7 episodes. They would have to drag the tournament stuff over 13+ episodes for that to serve as an endpoint. After Stain the next logical endpoint is the All Might fight.
So it makes sense for them to just go at a faster pace and hit that endpoint. They would have to cover roughly 72 chapters over 26 episodes which should be doable. They would be going from 22-94. It's pretty reasonable.
