The percentage of Krsna's 64 qualities that other expansions have is explained here.

The Percentage of Krsna's 64 qualities that His other expansions, direct (Visnu-tattva) and indirect (Siva tattva and jiva-tattva) have, is mathematically worked out here.

So how many qualities of Krsna His different expansions have, is worked out here as a percentage.

This percentage is based on the number of Krsna's 64 qualities (100%) each expansion has.

Visnu-tattva Forms and Visnu-"sakti"-tattva Forms of the Lord have 60 qualities of Krsna's 64 attributes which works out to be 93.75% of Krsna's 100% qualities.

Siva-tattva has 55 qualities of Krsna's 64 attributes which is 85.938% of Krsna's 100% qualities.

Jiva-tattva has 50 qualities of Krsna's 64 attributes which is 78.125% of Krsna's 100% qualities.

Siva-tattva (85.938%) between Visnu-tattva (93.75%) and jiva-tattva soul (78.125%).

Krsna ALWAYS has 100% of His own attributes in full, which is His 64 qualities, and this is why Krsna is Supreme Personality of Godhead and cause of ALL causes. 

Krsna is the ORIGINAL Form of Godhead from whom ALL His Visnu-tattva, Visnu-"sakti"-tattva,  Siva-tattva and jiva-tattva forms expand from.

This means the only difference between Srimati Radharani, Balarama, Maha Visnu, Ramachandra etc, and Lord Krsna is Lord Krsna has an extra 4 qualities MORE than all of them, although they may exhibit those 4 unique qualities partially.

Therefore, not even Srimati Radharani, Krsna’s consort, or Balarama (Krsna's older brother) always have those 4 extra unique qualities like Krsna always has perpetually.**
