Internal link count - best practice?

[STL]

When analysing our internal link count on our homepage we find we get different counts depending on the link counting tool used. We think this is because some tools include any duplicate links found on the page whilst others don’t.

1. Does google disregard multiple occurrence of the same internal link on a page?

2. And does it explain why you find differing best practice advice about acceptable maximum of links on a page sometimes being 100 or 200?

To answer the second question I think the reason for the suggestion between 100 to 200 of internal links is Google will crawl roughly 150 links per page before they may stop spidering. Moz says this internal link limit is pretty flexible and could be between 200 or 250 as well.

Google does not disregard multiple occurrences of the same internal link to the best of my knowledge. But with more links comes a reduction in 'link juice' that would be distributed to the other pages. So, you would be watering down your 'link juice' potential for your interior pages.
