Remember, SP two simply means there's 33% S character and 66% P character. SP three means there's only 25% S character and 75% P character. So SP two bonds are more stable than SP three bonds because SP two bonds contain more S character. So this Sigma bond within the double bond contains SP two SP two character. This bond, this covalent bond has SP two SP three character. And each of these three covalent bonds has SP three SP three character each.
