The slight dent in the foam seems to be exaggerated in the 'fully upright position'. with the lower cup 'properly' positioned high up over IMF, volume overflow crams up to just above this zone, like breast is trying to crawl out of the armscye. The closer down it's upper band is brought, the less this happens. Guessing immediate depth zone is not up to par with my root size, but has great overall depth, big surprise.
