Peach's Castle Hole 1:

This is only for the Front-Left Pin location (392y from Front Tees; 426y from Back Tees). This will work for any character that is capable of reaching the Green pipe far out left from the Tee Box you're playing from (See the BIG BOUNCE section below). After coming out of the other Green Pipe, you'll land 13.5-14 yards from the Pin. The second shot doesn't care about the Wind, since it is a putt.

If it is a standard Green, club down to the Putter and go with the Middle strength and hit the 64.4ft mark (one less than the 2/4 Middle mark). Aim just right of center. If it is a Tournament Green, club down to the Putter and go with the Middle strength and hit the 70ft mark (close to halfway between the 1/4 and 2/4 Middle marks). Aim just right of center. (You don't have to do this for Stroke or Match Play for some reason).

Yes, these do work and they are fairly generous, regardless of RNG. The hard part is getting through that Green Pipe! Only attempt this if you have a backup plan in case your shot to the Green Pipe fails (e.g. missed mark). Otherwise, you'll lose far more time than you may gain. But should you succeed, you'll have a higher chance of skipping two holes, which may amount to further time savings of 5-30 seconds (in addition to the 5-10 saved from this strat).

I've noticed that you don't have to change aim for Stroke or Match Play. I wonder if it has to do with the minor randomness of the landing point coming out of the second Green Pipe. There is minor variation, but you're going to be 13.7-13.9 yards away 90+% of the time. That still shouldn't explain why aiming straight doesn't work for Tournaments or Star Tournaments.

THE BIG BOUNCE STRAT:

This is a method to reach the Green Pipe with far weaker characters than you would expect. This involves an exploitation of the way Fast Fairway and Backspin work. If you have played this game for a fair while, you may have noticed that depending on the sidespin (including Fade and Draw) and Topspin or Backspin, the ball will bounce in slightly different direction. Try to imagine the ball rapidly spinning as it hits the ground at various angles and imagine what you think should happen to make sense of it. In a nutshell, topspin + draw/fade = lower rightward/leftward bounce, vice versa and etc. But the really interesting one for this strat is Backspin. This makes the ball bounce higher.

And what ties this all together is the Fast Fairway. It is a fantastic surface that amplifies the bounce and roll of the ball on contact. Thus, Backspin on Fast Fairway makes the ball bounce even higher, which allows this strat to be possible despite the Stopping Point simulation from Training Mode suggesting otherwise.

From Front Tees, it is possible for Wario (with a high straight shot), and everyone Daisy and stronger to bounce into the Green Pipe. Mario needs +1% or a tailwind of at least 4mph (2m/s) to make it since he can't add more carry to his shot by virtue of shooting straight. From Back Tees, it is possible for everyone Star Luigi and stronger to bounce into the Green Pipe.

While this shot is definitely slower than a typical drive elsewhere (even to Yellow Pipe, which is a decent alternative if you're having trouble playing to the Green in two shots), it can open excellent opportunities for a Birdie or even an Eagle Chip-in, which could make a difference if you plan to skip the 18th hole, or even a 2nd hole on top of that. Weigh your options and see if it will work for your style of play. Regardless, this is a cool strat and you should give it a shot, even if just for practice or casual play!
