What would be interesting to discover is: How many slaves were bought (ordered) and how many slaves arrived(delivery note). If 100 were ordered and 75 arrived as per delivery note then one could argue that 25% were lost due to horrible conditions.

In order to achieve profit, the owners of the ships divided their hulls into holds with little headroom, so they could transport as many slaves as possible. Unhygienic conditions, dehydration, dysentery and scurvy led to a high mortality rate, on average 15%[3] and up to a third of captives. Often the ships, also known as Guineamen,[4] transported hundreds of slaves, who were chained tightly to plank beds. For example, the slave ship Henrietta Marie carried about 200 slaves on the long Middle Passage. They were confined to cargo holds with each slave chained with little room to move.[5]

"About 15 percent of all Africans who made the voyage died, most from the accumulation of brutal treatment and inadequate care from the time of their enslavement in the interior of Africa. Others suffocated in the tightly packed holds, while some committed suicide, refused to eat, or revolted. Crew members, meanwhile, died at even higher rates, also mostly from disease. The victims of violence meted out by their officers, sailors in turn dispensed their own brand of terror to the Africans. For Africans who survived, the Middle Passage began with the separation from family and community and ended with a lifetime of enslavement."

"Between 10 and 15 million Africans were forcibly transported across the Atlantic between 1500 and 1900. But this figure grossly understates the actual number of Africans enslaved, killed, or displaced as a result of the slave trade. At least 2 million Africans--10 to 15 percent--died during the infamous "Middle Passage" across the Atlantic. Another 15 to 30 percent died during the march to or confinement along the coast. Altogether, for every 100 slaves who reached the New World, another 40 had died in Africa or during the Middle Passage."
You're looking at anywhere from 10% on the low end to 40% after it's all said and done...
There are also lots of good references to be found in the following link regarding the influx of Islam into the Americas via the slave trade:
