Let's say opposing team specifies staggered match times (two sessions). For example, 1st singles and 1st/2nd doubles at 1pm, and 2nd singles/3rd doubles at 3pm. Let's also say that they know they'll default one doubles line (we don't obviously). LLAR rules state that if you default a doubles line during your first session, and you don't have substitutes, you play the second session as specified in the original lineup. This technically means that opposing team, knowing they'll default one doubles line, can make it look like their 2nd line player(s) didn't show up, and default their 2nd line, instead of 3rd line. Unless we drop our 2nd team to 3rd line more than 49% of the time (which would be stupid), the opposing team has the advantage, because we have to stick to the lineup in second session, and can't move our 2nd line to the second session. I think that's a clear loophole in the rules. Or am I missing something?
