trying to understand top command -H option


I am running the top command to monitor the CPU utilization of a multi-threaded process. When I run the command with just the pid it gives me utilization of about 60-70%. However when I run top with the -H option, the cumulative CPU utilization of all the threads does not come anywhere close to 60-70% (it's around 14%). I am using a 4 core processor. Is there something that I'm missing here? Any tips on how to correctly interpret the information given by the -H option?

What is 14 * 4? Does that come near?
