Transacting users before HF20 vs after.

To gain some insights on the impact of HF20 on access to the STEEM blockchain, I ran a little script that looked at one simple metric: The number of unique transacting accounts per hour of the day. To get a usefull insights I rewinded to a few days before the hard fork untill just before the moment I made this post. I'll share my script below, but first, here is the data.
Let us first look what two normal days look like:

And now two days with HF20 in it. Remember, HF20 was supposed to activate at 15:00 on the 25th.

Most if obvious from the tables, but let us look at it in a little graph:

The above data was gathered using the below asyncsteem script.
