The information was not presented as viable tech paths but as the total tech cost of each faction.
This also highlights that Ostheer tech is both linear and has to practically unlock everything while gaining to little for doing so.
OKW FRP was included because the USF Major provides the same.
UKF Forward Assembly (250MP) was not included because it act as Ostheer reinforcement bunker+USF weapon racks+Artillery call-in+Garrison for emplacement and needs to be upgrade to FRP (200MP), and in my opinion would confuse things.
I think your point would become clearer if you show the relevant tech paths. You can also present the total cost on the side. However, everybody is going to skip all non-essential tech anyway (FRP, molotovs, mills bomb).
Otherwise, if you want to present the total tech cost for each faction, there is no objective place to draw the line. e.g.:
- include bofors or not (since OKW T4 is basically the same thing)
- include M20 or not, since every other faction has mines
- Reinforcement halftracks for Soviets/OST, since it counteracts 5-men upgrade for Brits, and FRP for other factions etc
However, for most intents and purposes the games are almost always over before the optional stuff is ever purchased
