Essence Holes, Bioware vs. Cyberware Options

[Ol' Scratch]

I noticed something odd in the rules this evening, was hoping to find some clarification.

Essence loss is split between bioware and cyberware; both are tracked seperately, and the whole subtracts from the character's actual Essence score. The reason they're tracked seperately is because the one that's smaller is halved for purposes of that final subtraction. So, what happens if down the line those numbers flip-flop?

Say you start with 1.0 points of bioware and 2.0 points of cyberware. After the game begins, you install a few pieces of bioware and now have 3.0 points of Bioware and 2.0 points of cyberware.

Using that example, does the new bioware have its Essence loss cut in half to maintain the original values? Do you suddenly have an Essence Hole in the cyberware departartment since it's now cut in half (becoming 1.0 of implants filling the original 2.0 hole)? Something else entirely?

In other words, is your Essence now 2.5 (cyberware -2.0 and bioware -1.5), 2.0 (cyberware -1.0 and bioware -3.0), or 1.0 (cyberware -2.0 with a 1.0 hole and bioware -3.0)?
