I may have looked at the topic titled and grazed over the subject matter a little there.

The question I originally answered/misread was that you were also enquiring about non-stealth situations. In those cases, using multiple leeches before the network reboots could be advantageous. Apologies.

Given the static visibility costs and reduced returns, multiple leeches on a single target seems to be worse value in stealth mode, but only until the

Leech reaches Level 7 due to a combination of reduced visibility and extra download speed. Don't forget to include the stationary network cost of an additional 20vis per second though! (Incoming copy pasta of excel sheet, did my best formatting.)
