The Alpha Miner skill plan includes Mining Frigate II and III; they have no level based benefits and the only use for them is that at level III you get access to Mining Barge. But Mining Barge is Omega only so it seems to me that there is no benefit to these skills for an Alpha clone who only needs to do level I for the Venturer.
Looks like a mistake to me, unless there is something about the skill not mentioned in info.
