1060 is too far
Because last Volume was Volume 98 & Cover was about Nine Scabbards
Volume 99 will obviously have a Cover about Worst Generation
And Volume 100 which is a Special Number/Milestone will definitely be about Straw Hats & ends with Chapter 1013
For remaining Volumes, we should have one about Beasts Pirates, one about Kaido & BM (If we get their Flashback), one about Final Round (Showing Kaido vs Luffy and/or Zoro + BM/Kid + Orochi & Momo/Hiyori)
So remaining Volumes for this Raid (After Volume 100) are imo 3, meaning it should end around Chapters 1040
Could be even less if Oda decides to rush things, so Chapter 1060 is a stretch
Volume 99 ---> We had Drake Chapter, Hawkins Prediction, Zoro vs Apoo, Ace talking about Supernova & Roof Battle ---> WG Volume
Volume 100 ---> Robin/Brook vs BM, Sanji Moment, Chopper vs Queen, Franky Victory Attack, Luffy/Zoro vs Kaido ---> SHs Volume
Volume 101 ---> We have Conclusion of Flying Six Fights & Focus on King/Queen, BM Fight & Kaido vs Yamato ---> Villains Volume
Volume 102 ---> We might have Kaido Flashback, Start of Final Round, Flower Capital in Danger ---> Kaido/BM & Wano Volume
Volume 103 ---> Conclusion of Final Round, Death of Kaido, Conclusion of BM Story, Onigashima Stopped ---> Raid Ending Volume
So imo ZKK should happen in Volume 103 or at Start of Volume 104 (At most but doubt it)
Meaning it should happen between Chapters 1035 & 1045
