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
