The thing is, how can she accurately gauge Stranges power?
Character statements can be suspect. But,
Children's Crusade has feats also. You have to remember, Dr. Strange completely failed to inhibit Wanda's increased power even with Xavier's help in the leadup to
House of M. Doom just ended up stealing that sh1t for himself.

Exactly what caused Strange's magic level to lessen?
Use of dark magic, loss of his own confidence due to recent failures, he's on the outs with Agamotto, etc.

Is possible to numerate the confirmed upgrades he received ?The Morgana Le fay is one.
Here are some of the more tangible upgrades at least:
Cagliostro taught him everything he knew in Iron Man #149.
Dr. Strange tutored him for days in Dr. Strange/Dr. Doom: Triumph and Torment. He also recorded numerous magical stances and incantations of other magicians during the battle for the title of Sorcerer Supreme.
He stole all of Ceranda's magical power in Thor Annual 1999 who, together with the Enchanters, would go on to mess around with Thor and Mjolnir.
It was revealed that he was tutored by Radu in Before the Fantastic Four: Reed Richards #2.
He honed his abilities of using the Dreamtime in Fantastic Four vol.3 #30.
It was shown that he stole magical tomes from another dimension to increase his arcane power in Iron Man: Legacy of Doom #2.
Like you said, he learned from Morgan le Fay in Mighty Avengers #9-11.
It was revealed that he stole and possessed the Book of Vishanti for a while in Doctor Voodoo #1-5.
It was revealed that he was taught by the Marquis of Death in Fantastic Four #562-569. It was also revealed that he spent years under the Marquis' unknowing tutelage as he masqueraded as his new apprentice. Which he only did after spending countless years upgrading his own sorcery in order to be able to disguise himself from the Marquis' senses.
Most of the time, he just shows up and uses new spells, reveals new proficiencies in a particular art, etc. And then sometimes he ends up expanding his knowledge. For example, he studied the Destroyer armor and dissected Asgardians in Thor #600-605. That led to him being able to strip and utilize the Odinforce.
