We know from various Forsaken POVs that Compulsion can be heavy-handed or subtle. Consider how hawkish Egwene became, and how constant Halima's contact was with her, and especially how Egwene befriended her when that is generally out of character.

The problem with light Compulsion is that it generally only nudges. So, nudge for headaches. Nudge for "Halima's not that bad, right?" Nudge for "Elaida certainly is the most important threat out there, isn't she?" Nudge for "Hm, the reports of what the Dragon Reborn is doing are pretty worrying, I don't know if I'd trust him."

Etc.

Not that this gives Egwene an easy out, since light Compulsion has to be subtle, and as we see from your articles she never really had a dramatic shift in character.
