Weekend afternoons (3–5 PM) ARAM Mayhem matchmaking different during those hours

Is it just me, or are weekend afternoons (3–5 PM) impossible for ARAM Mayhem? I consistently hit 6+ game losing streaks during that time, even though my morning games are fine. Is the matchmaking different during those hours, or is it just the 'weekend warrior' crowd? Would love to hear if anyone else experiences this.
