So, just for the record, if all the spiders in the world got together, they could eat a 300,000 pound whale in about 11 minutes. (Let's pretend for a second that they can eat every part of the whale, and I did my elephants-to-whales conversion math correctly.)

You run into the square-cube law here. There's nowhere near enough surface area to allow all the spiders access to the whale. Almost all will be looking at the back ends of the spiders ahead of them.

Now if you dispersed the whale carcass into a lot of fine bits, then maybe. That's going to be a lot of dynamite.

This suggests a smaller proportion of edible material from the larger whale.
The approximate exponent of 1.09 was derived from terrestrial animals, which support their weight on their bones. As HoneyBadgerDC mentioned, whales are aquatic and don't support their weight using their bones, so whale bones could be proportionally lighter than terrestrial animals' bones.

The Canadian Museum of Nature has a blue whale skeleton from an animal that is estimated to have weighed 80-90 tonnes. Based on the formula in your link (bones = 0.061 * animal1.09), the bones would be predicted to weigh 13,000-15,000 kg, but in fact they only weigh 2883 kg.

Actually, while I don't know off the top of my head about whales, some aquatic mammals have heaver bones than land mammals to act as ballast

This could be affected by the fact that whales do not have (significant) long limb bones.
