supplementary cards.

will some one clear up this rule for me please.

<strong>Any player&nbsp;may return a supplementary card providing that:</strong>-<p>    1.&nbsp; They play 18 holes of golf under Competition Play Conditions over a Measured Course. </p><p>   (This means that if there are more than two temporary greens or if the course is shortened by more than 100 yards you can not &nbsp;submit a supplementary card).&nbsp;</p><p>  2. The format may be either stroke play or stableford.</p><p>   3.&nbsp; Up to<strong> 10 supplementary scores</strong> can be submitted during the calendar year, <strong>but not more than 1 per week</strong>.</p><p>    4.&nbsp; Players must signify their intention to return a card before playing.&nbsp;&nbsp;</p><p>   5. &nbsp;Cards&nbsp;must be returned to the Golf Shop. (Failure to return a card is classifed as a No Return)</p>
