That's not what I'm saying. I'm saying that after the ship got stuck, they certainly incorporated the tides into their plan for how to unstick it. If the tides had been less amenable, they would have come up with a different plan.
So their plan didn't get "lucky", their plan was predicated on the tides being part of the solution.
That’s the point and the absolute bit of luck. Without the high tides they likely wouldn’t have been able to get it unstuck as quickly. Search for slope/fill volume calculation charts - the amount of fill required to be removed as you go deeper is logarithmic, NOT linear.
It was VERY lucky they had the highest tides possible.
Luckily it wasn’t nearly as high when it beached itself - but if it had beached itself on the downslope of the peak tide instead of the upslope it very likely would still be stuck!
Tide when it crashed was not nearly as significant as when it got free.
Imagine getting stuck during spring tide vs low tide hich is more than 2m lower and would have decelerated the ever given earlier
