While I feel that Blood Electrification is beneficial, I also believe that it alone is not going to do the job. Pulsing helps too.
But the one thing that I find is that full body zapping is needed to reach a lot of the virus. This requires a really good zapper with a 4 point contact system, 3 points positive to reach places that the BBBE does not reach.
You are correct to the point that a lot of zapping time is required.
