From where did you get the 0.95 * 16 * 1024 part?

The calculation of L1 is dependent on the size of your cache_dir, the
number of objects there will be, and the setting of L2. For simplicity,
the value 416 includes a L2 value of 256 and a average object size of 13
KB plus a margin of 100%.

L2 = 256

L1 = cache_dir_size/416 rounded upwards

Further, note that these settings only have a marginal impact on
performance.
