I think I’ll let the numbers do the talking.
I chose GMK Calm Depths as the reference since both are GMK, dropped recently and offers similar support
GMK Calm Depths Base Kit: 125USD (250)
GMK Jamōn Base Kit: 115USD (250),100USD (500), 90USD (1000)
GMK Jamōn Numpad: 38 USD (100), 33 (150), 30(250), 28 (500)
At Base MOQ, Calm Depths is cheaper (base case scenario)
GMK Jamōn costs 115+38=153 vs Calm Depths 125. Jamon is $28 more expensive.
In reality, Jamōn base kit is very much likely to hit 500 MOQ, with numpad at 150MOQ (likely case scenario)
GMK Jamōn costs 100+33=133 vs Calm Depths 125. Jamon is $8 more expensive.
However, if Calm Depths has a 500 MOQ option listed, it would probably be >$8 cheaper making it a clearer winner. In this case, I assume that the 500 MOQ price discount of Jamon is attributed to its cheaper and more attractive base kit price (and disregarding the factor that Jamon is run on MD which probably also bumps up its number by a bit)
The cost difference benefits 75% of the community and disadvanatages 25% of the community (113 numpad sets/391 base kits sold).
If the entire community was to be taken as a whole, there are savings.
GMK Jamon average price: 0.75*100 + 0.25*130= $107.5
This is, on average, a purchaser saves $17.50 (125-107.5=17.5) (again assuming if the community is a Single entity!)
In conclusion, there is clear costsavings for the community as a whole if numpads were split but yet there is no clear option at the subgroup level (numpad vs not numpad user) since 25% numpads is a sizeable minority, and yet 75% non-numpads is a sizeable majority too
