Character Generation and cyberware, Clarification of some rules Options

[Omenowl]

I have been reviewing character generation and have a couple of questions that I thought I knew:

The first is when you get an adept or magician and you get cyberware is the magic/resonance rating calculated before or after the inclusion of cyberware.

The question arises from this statement in the rules

Note that any attribute boosts gained from implants do not affect
other aspects of character creation—a boost to Logic, for example,
does not increase the Knowledge skills you start with.
Any reductions to a character’s Essence will also affect his Magic
or Resonance (see p. 177).

Does this mean the essense loss is a maximum attribute with the associated +25 for the highest attribute, or does it mean the player buys the magic/resonance attribute up and then as he adds essense it drops during character creation? I have been using the latter interpretation, but now I am not sure if I am applying it correctly.


The next question which comes into effect is the use of cyberware and essence loss. Are the multiplier reductions added or multiplied

For example:
Our runner has
A suite for 10% reduction
Alpha ware for 20% reduction
Biocompatibility 10% reduction
Adapsin is 10% reduction

Now if we multiply everything out we get 0.5832 and if we add the reductions we get 0.5 essence cost. For deltaware it is a bit more extreme with 0.3645 multiplied and 0.2 for added.

It gets even stranger when you include alphaware with secondhand because if you add then it has a cost of 1, but if you multiply then you get 0.96 essence loss.
