TC1-alike

This is an experimental variant proposed by Admin. Both cores are 2 hours long and placed early so that the first nap can be placed in the morning. The second nap is placed around midday. This resembles TC1, replacing one of the cores with a nap while extending the other cores. The dawn nap may increase dream recall. This variant has only one daytime nap, which may make it more convenient for some. Nonetheless, the early first core may pose an issue.
