Hello Cormac.
Thanks for being in touch. I think, suffice to say your concerns are highly likely to be meaningful, judging by the advice given by Steve, and what appears to be splattered about any enquiry you are likely to find on a search.
If it were me, I would be taking this as read, and making your decision based on this. If it happens to schedule, then you will have made the right decision. If it doesn’t materialise according to any important-to-you timescales, then at least you won’t have made an irrecoverable decision.
No such thing as a stupid question:- I can recall a quote some decades ago by a then Technical manager at VW - ‘I wish I understood everything I know!’
So true - we may often have the right answer, but perhaps seldom the in-depth understanding and logic of the explanation.
Kind regards,
Gareth.
