MOP, help needed to understand the total status

[otahirs]

Hi, I am implementing support for total results after X stages for OResults and I have encountered a minor problem.
the XSD describing the MeOS online protocol looks like this:

<xsd:complexType name="Input">
    <xsd:annotation>
      <xsd:documentation>
        Input status.
      </xsd:documentation>
    </xsd:annotation>    
    
    <xsd:attribute name="it" type="xsd:integer" use="required">
      <xsd:annotation>
        <xsd:documentation>
          Input time, i.e. accumulated time of prevous races/legs/stages etc., in tenths of a second.
        </xsd:documentation>
      </xsd:annotation>
    </xsd:attribute>
    
    <xsd:attribute name="tstat" type="xsd:integer" use="required">
      <xsd:annotation>
        <xsd:documentation>
          Total status of the competitor after this race/leg/stage etc.
        </xsd:documentation>
      </xsd:annotation>
    </xsd:attribute>    
  </xsd:complexType>

If i understand it correctly, the tstat should be total status of the competitor after this race/leg/stage etc.
However the output from recent event contained records like this

<cmp id="14923505" card="533135">
<base org="142" cls="185280" stat="3" st="381000" rt="50430" nat="CZE">Snow, Radek</base>
<input it="26210" tstat="1"/>
</cmp>
<cmp id="263877022" card="42057">
<base org="48" cls="185283" stat="0" st="403800" rt="0" nat="CZE">Vomáčka, Oldřich</base>
<input it="40120" tstat="1"/>
</cmp>

It does not make sense for the competitor to have MP status stat 3 and total status OK tstat 1.
or to have status Unknows stat 0 (still running), but total status tstat 1 OK

---

more over, if results are send only for selected stage, the total status always shows <input it="0" tstat="1"/> for every competitor, even when the competitor has not finished yet

<cmp id="256" card="8014049">
<base org="2796" cls="4" stat="0" st="388800" rt="0" bib="24">Novák Matěj</base>
<input it="0" tstat="1"/>
</cmp>

It would be grateful if you could clarify the implementation of total status in MOP
