CS2 API: maps[] empty and point-in-time semantics of /matches/{id}/stats/

Hi Bzzoiro team, I'm using the CS2 API (Sports Addon) for internal backtesting research, and I have three questions. 1) maps[] is empty for finished matches In GET /csgo/api/v2/matches/{id}/, the maps field is present but empty ([]) for every finished match I sampled: 40 finished matches spread from December 2025 to October 2026, including ESL Pro League Season 24 matches, across all ages. The docs show a finished best-of-3 with three maps. Is maps[] populated for CS2 matches at all? If so, which matches have it, and is it restricted by plan or tier, or is it a known data gap? 2) Are /matches/{id}/stats/ values frozen at kickoff? The docs say the endpoint returns how both sides were playing "going into the match". For a finished match, are form_results, map_pool, head_to_head and the aggregate rates (map_winrate, round_winrate_t/ct, pistol_winrate, opening_conversion, first_to_rounds, kd_ratio, avg_damage): (a) stored when the match was collected, before kickoff, and never changed afterwards, or (b) recomputed on request using only data from before the match start, or (c) computed from current data at request time? Is there any timestamp field (for example as_of or computed_at) that tells me when these values were calculated? What time window do form_results, the aggregate rates and map_pool use? (head_to_head recent_matches is often an empty list even when total_matches is above zero; is that expected?) 3) elo_rating and player-stats Is team elo_rating only the current value, or is there any way to get the rating as it stood before a given match? What does elo_peak mean? For /matches/{id}/player-stats/, are the stats and percentiles computed as of that match, and over what window and population? A short answer to each would help me a lot. I'm also happy to share example match IDs. Thanks, Gigi
