Calculating BPM with inputs Program the shortest code that will calculate the average BPM (Beats per Minute) using 8 data points of time passed. This is my first post, and I haven't seen a question similar to this. Since I am a fan of rhythm games, it would be nice to have a small handy tool to calculate BPM using your own keyboard and your own sense of rhythm (if you have one...)
Challenge

All inputs must be singular. (i.e. Only pressing &quot;enter&quot; as &quot;input&quot;)
Your program must take at least 9 inputs. (To create 8 data points of time passed.)
Your program should output the BPM of the keypresses rounded at 2 decimal points. (i.e. 178.35)
Timing starts at first input. Not start of program

This is code-golf, so the shortest answer wins.
Example Input and Output
Provide at least one example input and output. Make sure they match your own description of what the input should look like.
Input:
&gt; [Enter-Key]
# User waits 1 second
...  7 more inputs
&gt; [Enter-Key] 

Output:
&gt; 60

You have to press enter 9 times. (Also works in Octave.)
