Ray's advice on waiting for bleed water is good but that's not really your swirl problem. A 24 inch trowel run too early will spin marks into the cream no matter how wet the slab is, because the pan is too big for the mud to hold up under it. Small machine first, 36 inch, low pitch, high rpm, and keep moving. The uneven drying you saw at the dock edge is a separate thing, wind pulls moisture off the perimeter way faster, so set up a wind block or wet those edges down while the middle catches up.

Wagos all day. Tape just hides the heat.

Wait, you think hitting 1,000 is the part that should make you slow down? I see it the other way. Your body gave you that signal way before tree 1,000, probably around 600 or 700, and you pushed through it anyway. That's not dedication, that's just ignoring what your back was telling you for years. I get the counting thing, lots of guys track their cuts, but the number isn't the problem here. The problem is you needed a round number to finally listen to your own body saying stop. Your back hurts after every third removal at 47 because you kept going when it hurt after every fifth at 44. Anyway, congrats on the oak.
