Narrative:

While on a personal flight; I inadvertently penetrated the tfr referenced in [an] fdc NOTAM. Before every flight I always check the FAA's tfr page and check weather and notams through [computer software] and this flight was no exception. I was fully aware of the tfr which was in effect however in this case because of the unclear format in which the tfr was drafted; I misunderstood the affected areas. NOTAM listed two affected airspace areas; area a and area B. Airspace B was very clear in that it affected an area defined by a 7 NM mile radius off the lga 271 degree radial at 5 NM miles. However airspace a was where my misunderstanding lies. In this case; instead of defining the affected airspace as the lateral limits of the new york class bravo airspace (which is what the affected area was); 50 separate latitude/longitude points were referenced. Because of the way the points were listed; it took up a full screen on the computer to view. However; when I scrolled to the bottom of the list; I saw what I thought were the affected areas which was a 3 NM radius off the dpk 241 degree radial at 5.3 NM and a 3 NM radius off the cmk 215 degree radial at 12.8 NM. What I later [determined] is that these were the excluded areas and not the affected areas. Because of this misunderstanding; I estimate that I penetrated the southern edge of the airspace by two or three miles.I would like to make it clear that this was not an intentional deviation. This was just a personal flight that I could have taken in any direction. I have been flying for [many] years and dealing with tfr's is nothing new. If I had any hesitation about whether or not I understood the tfr; I would have stayed away from the area or contacted ATC. I was certain I had read the tfr correctly and feel that if it would have been written in a more clear fashion stating that the affected area was the lateral limits of the class B airspace instead of fifty separate latitude/longitude points; this could have been avoided.

Title: A local Pilot; familiar with the area and TFR NOTAMs; was confused by the format and depiction of the TFR area; and unintentionally entered the area. He added that a clearer presentation of the affected area would likely have prevented this encounter.
