If we were arguing rules in SR5, then yes, I would fully understand (and would fully agree with) your concern.
For SR6 however, in many instances you are unfortunately almost required to have knowledge about how we used to resolve them in previous edition in order to correctly resolve them in SR6. In many cases SR6 seem to be focused on RAI more than RAW.
Yes, there are no clarifying or redundant rules talking about the device rating table (as we had in SR5) and the clarifying [but perhaps redundant] table with guiding examples (that we used to have copies of in both in the Matrix Chapter and the Street Gear Chapter) is also missing. But the intent seem to be that we should still use the guidance from the device rating table we had in the previous edition (even though it is not actually spelled out, or rather because there is actually nothing spelled out indicating the
opposite).
yes the chart is still applicable, but no it has not appeared in any official printing... yet (but it is coming just don't know when)
Thank you for confirming :-)
