Or, & this is just me theorizing, prior to 010 & 011, the project focus was more on mind manipulation & telepathy, as we see with 001 & 008's more frequented powers, BUT after some incidents, like 008 escaping (Probably with mind manipulation) & 001 ending up doing something that made it necessary to install an inhibitor in him, the lab decided maybe honing those kinds of powers... not the best plan for a containable group, & then afterward focused more on telekinesis & astral projection... Not that it would matter much, once they begin to independently self-actualize, like 001 & 011 are doing right now
