Correct. On primal you have: 2793 posts (including reposts) + 7657 replies (10450) On nostr.band you have: 10175 posts and replies + 127 reposts (10302) so your stats are missing 148 posts, replies and reposts which I assume is approx equivalent to the last few days for you. For me it's less than 20 different but that fits well with the time the graph starts to flatline.
