Computational makes it easy..
You hammer the throttle during crash dive then cut power and hard turn stbd or port. you should have enough momentum to avoid Fido.
Computational means that there has to be an assumption on the the noise level of the props, and as
hinted , 1 knot seems to be the cloaking speed. Thus Fido locks onto the last known bearing before you cut the throttle.
Having momentum ensures that you get out of the way.... sort of
