"turn double play" is that just hte guy catching and "Turning" the play... the first guy just feeds it to the bag, that should be virtually no different than normal.
if not, yeah it might be an issue, but should not affect range. a slight increase in throwing errors, but shouldn't be hugely significant. it simply shouldn't affect fielding errors.
3b only requires a 30... just how often do they start DPs - and that's even if that is considered (starting as opposed to turning) as i postulate above. if it does include that portion it's misnamed.

it's silly to say sorry in this context. be assertive and just start expressing your argument. it's nothing personal.
