example error: Converting simple addressing to explicit addressing

[3052]

http://dashif.org/Guidelines-TimingModel#addressing-simple-to-explicit

the example gives this math which is correct:

SegmentCount = Ceil((900 - (-0.5)) / (4001 / 1000)) = 226

but then it says this:

Set S@r to SegmentCount - 1.

which should be 225, but the following example incorrectly uses 224:

<MPD xmlns="urn:mpeg:dash:schema:mpd:2011">
  <Period duration="PT900S">
    <AdaptationSet>
      <Representation>
        <SegmentTemplate timescale="1000" presentationTimeOffset="900"
            media="video/$Number$.m4s" initialization="video/init.mp4"
            startNumber="800">
          <SegmentTimeline>
            <S t="400" d="4001" r="224" />
          </SegmentTimeline>
        </SegmentTemplate>
      </Representation>
    </AdaptationSet>
  </Period>
</MPD>
