elif big_site_method == "bigdrt":

In this line, there's big_site_method "drt" and "bigdrt". However there's no explanation in https://block2.readthedocs.io/en/latest/user/keywords.html#

Thank you.

The big site method drt is the "distinct row table" approach. The explanation can be found in #113 (comment). bigdrt is an alternative implementation of drt which may have worse computational performance and higher memory consumption, so it is deprecated.

All undocumented features in block2 should be considered experimental and untested.
