Question for any weather guru's out the

I have had a wonderful season so far this year. I've had many 4-5
hour flights cross country. I'm trying to figure out the XCSkies
weather features. The CAPE has shown 0-300 almost everytime I've gone
soaring so far this year. It's never above 0-300 but yet I still can
have great cross country flights.

Does the CAPE (Convective Available Potential Energy) matter when
reading the weather forecast?
