Well I have no objection to it, and wouldn't be surprised if I had used it. I think I might prefer something less dry, as in your 'What I understand...'.
On the basis of that verb, but maintaining the grammatical function of inference, you could also say 'My understanding is....'.
You could also demonstrate your appreciation of the difference between 'implication' and 'inference' (and earn several Brownie points in so doing) by saying 'The implication of what you say is that...'.
