Re: Is it a error in doc?

From source code, I found the formula as below:
-------------------------------------------------------------------------------
if (auto_buf_pool_size_in_gb < 1.0) {
;
} else if (auto_buf_pool_size_in_gb < 8.0) {
srv_n_log_files = static_cast<ulong>(round(auto_buf_pool_size_in_gb));
} else if (auto_buf_pool_size_in_gb <= 128.0) {
srv_n_log_files =
static_cast<ulong>(round(auto_buf_pool_size_in_gb * 0.75));
} else {
srv_n_log_files = 64;
}
-------------------------------------------------------------------------------

The automatic configuration algorithm of innodb_log_files_in_group is so simple and rude, and now, could this be considered a source code bug?
