I was not sarcastic. Studies like http://www.tik.ee.ethz.ch/file/49318d3f56c1d525aabf7fda78b23fc0/P2P2013_041.pdf http://www.tik.ee.ethz.ch/file/49318d3f56c1d525aabf7fda78b23... have shown that 5% of nodes with a regular internet connection still haven't received the block after 40 seconds; and the median time is around 13 seconds. The sat latency at 1-2 seconds is much lower and would hugely improve block propagation delays.
Edit: a second paper (2016) has similar findings: 10% of nodes haven't received the block after 79 seconds: http://fc16.ifca.ai/bitcoin/papers/CDE+16.pdf http://fc16.ifca.ai/bitcoin/papers/CDE+16.pdf
