I don’t think that would mean that they’d necessarily have 90 TC places for vac schemers though... they realistically know that not everyone who does a vac scheme will get a TC. Also people will have to hear back about TCs before the vac scheme because there’s another TC recruitment before the summer vac scheme. Also the vac scheme is made up of different potential intakes with people in penultimate and final year and people doing law and non-law so it’s not as straightforward as the individual numbers suggest.
Yes, they take 100 people for both intakes together and not everyone on the Winter Vac scheme got a TC, plus there are a limited number of TCs available outside of the VS. I do think there is some correlation between the VS and the amount of direct TCs and that might result in some people having to wait a bit longer, but as with everything, nobody knows what really happens
