This is truly nice data and analysis.

If I may add something, as a upvote hungry Steemian, I might be interested in additional analysis such as these...

Taken from your data here:

We could get these data...

dApp	Avg Vote Worth	No of Votes	No of Authors	Votes per Author	Tot Vote Worth per Author
dlive	10.46	8388	1845	4.55	47.55
dtube	34.97	2163	532	4.07	142.18
dsound	11.22	3379	265	12.75	143.07
steemhunt	1.47	25204	1251	20.15	29.62
Steempress-io	4.75	6922	801	8.64	41.05
Utopian-io	7.10	4556	1321	3.45	24.49
tasteem	2.44	12332	1505	8.19	19.99
busy.pay	1.13	18150	1285	14.12	15.96
fundition	57.48	256	101	2.53	145.69
esteemapp	1.12	12753	2883	4.42	4.95
Steemit-jp	1.74	4486	423	10.61	18.45
sndbox	2.35	2615	1138	2.30	5.40
Mack-bot	-0.04	45749	660	69.32	-2.77
spaminator	-4.49	3342	505	6.62	-29.71
steemcleaners	-8.65	2203	773	2.85	-24.65

With the above data we could get several conclusion such as:

• The biggest amount of (down)votes are given by mack-bot, however these are concentrated to several authors only wherein average each author gets 69 (down)votes.
• @good-karma 's @esteemapp is better in distributing votes where each author gets around 4 votes only while distributing it to almost 3,000 authors.

Another data that I may find interesting but do not know how to get it is the comparison of total users per dapp vs the users who are upvoted.

Anyway, again, the data and analysis you've provided are very useful. Thank you for this.
