The secp256k1 endomorphism is very efficient (a single field multiplication), so when using the endomorphism in a scalar multiplication of point P, the lambda-P precomputation table can be generated much more quickly by simply applying the endomorphism to the P precomputation table (instead of precomputing from lambda-P).
