The APRS digipeater have always been set up to act upon both the "RELAY" and "WIDE" style aliases. I emphasize these generic names, as they are not actual aliases in use anymore. All high digipeaters need to be able to act upon the usual WIDEn-N alias, of which WIDE1-1 is a subset. Fill-in digipeaters which are designed to help low powered stations into the main digipeaters should only act upon WIDE1-1. When you are running a path of WIDE1-1,WIDE2-1 from your low powered handheld/mobile station, you are asking for 2 hops, with the option of having the first hop going through a fill-in digipeater. If you are within range of a high main digipeater, then your first hop will be through that main digi. There's no need to have fill-in digipeaters inside the footprint of a strong main digi, just to handle the WIDE1-1 path elements. The whole reason behind using the somewhat confusing WIDE1-1 alias for fill-in digipeaters is so that the main digipeaters WILL act upon that element using the same anti-duping routine that the usual WIDE2-2 or WIDE3-3 path elements activate. The use of WIDE1-1,WIDE2-1 as a "normal" path request is a work around to get the main digipeaters to give 2 hops, one when the WIDE1-1 is acted upon, and a second when the WIDE2-1 is acted upon. It is functionally equivalent to WIDE2-2 as far as the main digipeaters are concerned. The explicit WIDE1-1 element allows fill-in digipeaters to boost only on the first path element. If we ran WIDE1-1,WIDE1-1 as an outgoing path, then you could end up activating 2 fill-in digipeaters in a row, 2 main digipeaters in a row, a fill-in digipeater then maindigipeater, or a main digipeater then fill-in digipeater. There is a method to the madness! James VE6SRV
