Rebound seems to be underway

I am an academic researcher on cryptocurrencies. Lately, I have found that TTC's blockchain exhibits some unexpected behaviors that I cannot find in the source code. Several non-premined blocks have rewards much higher than stipulated. For example:
block_reward difficulty timestamp
block_height
1779 18009 7.805143 2014-02-01 18:08:39
1819 18008 6.574982 2014-02-01 20:14:57
1949 18038 7.750942 2014-02-02 03:19:27
2372 18010 2.374759 2014-02-03 02:11:18
66574 12598 0.207160 2014-07-21 08:44:00
66696 11658 0.313181 2014-07-21 14:29:27
Their neighboring blocks all have rewards 8008 (plus fees), which is expected, according to TTC's source code.
This might be an error within BlockExperts explorer.
There was a premine here...

That might be what you are seeing.
We have had to roll to v1.6 recently because our update failed for version 1.5 that should have reduced the mining reward to 3003 and change diff algo to Dark gravity wave.
Other than that everything is pretty much as is.
If you find something I cant I'd be happy to know, I will forward this to one of our other devs for clarification.
