That's right, we (the developers of the site) think the numbers should not be taken too seriously, but they help to order the evidence for and against in terms of strength. Any simple format for presenting information will have its own biases and an evidencechart will have many limitations, but we think it's nice that it's so concise relative to prose. A full argument map would provide more logical structure, but is much more difficult and time-consuming to create.
