DLF Sohna: Super area ka sach kya hai?

Sector 23 Sohna, just moved into my DLF flat last month. Honestly, super area ka calculation abhi bhi confuse karta hai. Possession ke time laga ki carpet area toh thoda kam hai expected se, but payment pura super area pe hi hua. Builders ka yeh super area trap kitna common hai yaar? Kya koi isko avoid karne ka tareeka hai?
