Hi TANOTFA, really excited someone has been closely following my posts on this! Yes it hit that alternate target perfectly, thanks for pointing out, it saved me a follow up post to update. I'm also impressed with your very neat chart.
I've spent more effort as a student of price than time, so I don't always get timing right and have needed to adjust this one. You've got some really interesting symmetry going there though with that 87.5% time extension matching an 87.5% price retracement. I just learnt something, I'll have to look into this further.
You've also raised an interesting point about >5% fall below high has 80% prob of not coming back, if I'm interpreting that right. I haven't considered that sort of rule before.
