I counted the CLT results at 6/5/2 for David Kelsey/Dave Kelsey/David P. Kelsey right now.
Link: http://www.imdb.com/name/nm0447038/.  T!M says that the common name is Dave Kelsey.  I would like to be sure (no offense T!M).

'The Butchers Wife': David P. Kelsey.

'Kingpin': David Kelsey.

The 'Mission: Impossible II' credit is questionable: he's not credited as part of the main crew, but under some additional unit. And the rules say: "Do not enter unit crew".

For the record: it would be extremely good if his common name was not "David Kelsey", because then that would distinguish him from the actor named "David Kelsey" (link). The problem is that there's no alternative way of differentiating between them, since no birth year is known for either of them.

'Bruce Almighty': Dave Kelsey.

'Dick Tracy': Dave Kelsey.

'Kingpin': he's the very last in my list of art crew. Screenshot:



And I'd count his 'CSI NY' credits as one title. Especially since, as explained before, the common name is the only thing we've got to differentiate him from other people named David Kelsey.

I'll try and check some more...

BASEketball = Dave Kelsey as Special Effects

'Dude, Where's My Car?': Dave Kelsey.

Quoting huskersports:

Quote:
I'd count the CSI titles as 1, but I've had numerous instances where a crew member is credited 2 or 3 different ways over the course of just 1 season, let alone an entire series.  So I count each season as 1 entry.

To each his own - unfortunately, there is no official stance on this. I count them as one, making Dave Kelsey the common name (currently 6 titles vs. only 4 for "David") as far as I'm concerned. Which, as pointed out earlier, is quite a good thing, because it happens to be the only way to distinguish him from other people named David Kelsey in our database. So, as far as I'm concerned, the current balance is this:

The big problem is it looks like it all depends on how you want to count TV series. Although even if you count CSI:NY as 1, it's still not decided as there are enough pending titles to make David Kelsey the winner if they all end up with that credit.

There's still a pending title under David P. Kelsey as well, so technically David Kelsey could end up with 7.
