What's your LMSC policy on Top Tens?

In Pacific, we only count times swum in Pacific sanctioned meets for our Top Tens and Records. I was wondering if your LMSC counts times swum at Nationals, or in other LMSCs, in your LMSC tabulations? This has always been frustrating for me, especially during LC season, as we usually only have one or two meets. Last year and this year we had one meet, our LC championships! I would love to be able to have Nationals times count, and/or be able to enter meets in other LMSCs and have the times count in Pacific tabulations. If you respond, could you tell me what LMSC you're in? I'm going to present "my case" at our May meeting. Thanks : ]
