Getting a little off topic here and purely academic as I've no need to actually do it, but do you have any idea how it actually works if you change cable types?
E.g. If I ran 39 glass fibre, then one gold (1eu/~2blocks) and then another 39 gfc, would I get any power loss at all, and how is it calculated?
Each cable has a set amount of EU that it loses per block. Glass Fibre and Tin lose 1/40th of an EU, Copper loses 1/4th of an EU, Gold, Splitters and Detectors lose 1/2 EU (I believe?) and HV Cable loses 1 EU unless properly insulated in which case it can be marginally less. The EU loss from all of the cables in a line is added together while the packet of EU is being sent from a generation/storage device to machines that request it. The number is then rounded down to the nearest integer, and this integer is then subtracted from the sent packet to calculate the total amount of EU being sent.
To answer your question, in your example, you would lose about 1 EU per packet sent.
Also, this works the same regardless of whether it's a packet of 1,000,000 EU or 1 EU. Thus, packets of 1 EU being sent along a line of >40 GFC/Tin, >4 Copper, >2 Gold/Splitter/Detector or >1 HV Cable would disappear entirely before reaching the machine although they only lose 1 EU per sent packet. Packets of 1,000,000 EU would be reduced to 999,999 EU/p. Thus, loss can be much more profound/noticeable with smaller packet sizes, especially machines such as Solar Panels and Water Mills.
