Also add to the fact tsunade was optimal during the fight with Madara, but ran out mid fight only for dan to restore some, then when they were wounded she used even more to summon katsuyu and heal the others while katsuyu had to divide up her own chakra to also heal her, the others, and maintain the summoning so she didn't go away. It's like tsunade was at 100% at the start of the Madara fight and it's only gone down, tsunades been through a lot in the last few hours by all means, its like she was at half capacity when the 5 kage arrived and she spent the rest of her energy with sakura (who by all means had more as she didn't have a preflight and her seal activating mid battle increased her available reserves) so in one way it made sense why tsunade couldn't heal naruto, her energy was going up and down in the last couple battles and events, sakura is nearing the end of her own resource though even with the nine tails shroud still on her, maybe it supplemented her, but I enjoy how sakura is doing everything she can even seemingly hurting herself to exhaustion to try and save naruto,Yup, pretty much.
Not to mention Tsunade hasn't been on the battlefield as long as Sakura was.
But all I'm saying is tsunade has been through a lot more in the past few hours, she hasn't been optimal during the fight at the obito, Madara, ten tails sight.
