While the effectiveness metric is a great means to compare campaigns, the score itself is only

applicable to the first few advertisements in each medium. For example, Social Media has an

effectiveness metric of $100$ and a reach to $14,000$ new customers per ad$.$ These scores are only reliable

for the first $14$ Social Media ads. After $14$ ads, the benefit declines. For purposes of analysis, you can

assume that the effectiveness metric for Social Media drops to $65$ and the potential new customers

reached drops to $5000$ per Social Media ad beyond the first $14.$ For Satellite Radio ads, the

effectiveness metric is only reliable for a maximum of $20$ ads. After the $20$ ads, the effectiveness

metric declines to $20$ and the number of new customers reached declines to $3200$ per ad$.$ Similarly,

for Music Streaming Services ads, the effectiveness metric is only reliable for a maximum of $27$ ads;

the effectiveness metric declines to $8$ and the potential number of new customers reached declines to

$1000$ per ad$.$
