The last numbered round of each year since 2019 is as follows
2019 — 611
2020 — 692 (+81)
2021 — 763 (+71)
2022 — 841 (+78)
2023 — 918 (+77)
This should mean that at the end of 2024 it is estimated to have about 994-999 numbered rounds. Quite a decent chance that #1000, the millennium contest, occurs when the magical tab is activated, possibly the first contest of 2025
