Do you mean BIP141?
Your example is an error by BIP141:
1*4 + 79999*1 = 80003 > 80000

Subject: [bitcoin-dev] BIP147 minor error
The BIP147 reads:
Sigop cost is defined. The cost of a sigop in traditional script is 4, while the cost of a sigop in witness program is 1.
The new rule is total sigop cost ≤ 80,000.
But the code implements:
if (nSigOps + (nWitSigOps + 3) / 4 > MAX_BLOCK_SIGOPS)
... error....
Which is not the same.
For example:
nSigOps = 1
nWitSigOps =79999
Is not an error by BIP definition but it's an error by the implemented code.
Regards, Sergio.
