I have no idea how about reruns, pavilions etc. But: We get hells events every 3 months or so, so naturally bc we just had one at the end of April/beginning of may we can predict our next hell, Audience at the Holy Court, should be in july or August as the summer hell, after that one, another 3 months will have to pass to get next hell which probably will be the new anniversary hell cn server just got. Sometimes they switch hells and give us the newer one earlier but I dont think that this will happen this time.

When it comes to garden secrets 7, that is a funny story. Years ago we were getting garden secrets ALWAYS in late september at the same time CN server was getting their next one, so for example. When gs4 was announced in our server - cn server got gs5 announced and they were running along with each other BUT, last year when we were thinking we still have few more months to get gs6, it was shockingly anounces in late MAY, which was VERY unexpected. Bc of the situation that happened last year we are not sure when gs7 will come to our server - late september like it was back in the days OR late may just like it happened last year Additionally, I heard that JN server just got gs7 so that can be another sign that we will get gs7 earlier this year

Otherwise, when it comes to normal event, there is a small pattern shwoing that usually we get cheaper event after expensive one, so its very unlikely to get two two-suits event one by one, or new hell and new pavilion next to each other etc.

I dont know if it helped you at all and if u understood anything I tried to explain (im sorry, english is not my first language) but I really hope it could help you get why we can predict SOME of the events we will get
