A perfect double would have a 4th ♥

A perfect double would always be 1-4-4-4; so, what? We aren't always dealt perfection, so we do what we can with what we are dealt. It is close enough, IMO, that the hand is suit-oriented with support for the non-spade suits --and sucks for NT unless partner can bid NT from that side.

It is also close to a NT overcall, IMO, even though Double would be my choice for those reasons.

This is a difficult decision. I hate to make a T/O X with 3 small in the other major.

It is possible to rightside notrump by bidding it ie JT9 or QTx on a good day but an advantage to me is when lho bids 2♠ and pard can compete on some scrappy hands that include a takeout double where we can avoid the poor 4-3 heart fit.

I know the downside and consider the choice in the 49%-51% range either way.

Prove your math. I calculated 48.87%-51.13%.

That's the calculation for double. I was cutting you some slack.
