Definitely +1
I had the whole spreadsheet of gear demand, that is composing all direct and indirect demand (that was before the last round of characters).
Your analysis is spot on, the demand number for Droid Caller Mk3, Keypad Mk4 and PowerCell Mk5 are in the 5000's (for a whole roster fully geared).
Not to look too depressing, but this is somehow still dwarfed by the infamous Stun Cuffs Mk3, Carbantis Mk3 and Haridryers Mk6 (in the 8000-9000). Even with the challenges, we're talking about 3+ years worth of grind.

(The numbers in the colored cells are the accumulated demand in pieces for a gear)
On the adding insult to injury side, the Tanks challenge keeps giving me stuff I already have enough to equip the whole demand 2 or 3 times over, like that MedPac Mk1 (total demand is 600, I have 3 times as much), or that new Binoculars Mk8 that was simply pointless for so long, and not much less so right now.
