I can share my timeline:
2015: applied
2016: got my first card, which was 1 year at that moment
2022 February: applied for citizenship. Was delay in card renewal in 2021 due to covid related backlog, and lawyers recommended to renew first, than apply. Managed to renew in 2021, which is the rare case, just lost about 6 months
2023: the process was stuck until renewal. Autorenewed in November, got new contagem de tempo and sent to IRN in Jan 24
2024 Feb: favorable decision, but system delay in creating registry and birth certificate
2024 June: got citizenship
My spouse with the same timeline received request for extra documents in February, those were sent immediately, but he is waiting so far
