I tried to break this whole correction down. In my final wave 5, subwave 3 would not be the shortest if subwave 5 hits target 1 and not 2, if wave 1 is longer than 3. If 3 is longer than 1 which I find hard to say with certainty, target ~3600 looks possible to me.
Many TA say we are going to 9k very soon, this would disprove my count but i'm pretty sure we won't pass 8700 until we go down again.
These are just my thoughts, i'm still learning and would love to hear criticism (either + or -)
