You make good points, but mistake 1 key word "yet". They only said during Rias's match. During her training it was already proven she has potential possibly genius level at a fast past time ready enough before the next match. Strategy wise especially for the next match I think it's a good choice. The fact that first real member besides trades is his queen, the fact that Grayfia won't participate anymore, that Ingvild personality alone wanting to help Issei and that she is unknown character to the Azazel Cup,  has the ability to strengthen others which is crucial for the finals seems the prove that theres a really good chance that Ingvild will compete in the the tournament.
