 Revised numbers can be found here: [http://www.ast.cam.ac.uk/ioa/wikis/gsawgwiki/images/6/66/Supernovae_alerts.pdf]. The bottom line is that the total SuperNova catch is more like 19 down to G=19 (2000 before maximum), and
 about 200 will be brighter than G=16. A figure is reproduced here.

-They selected a subset of 105 light curves well-observed in both rise and fall portions of the light curves and developed a '2-stretch' fit algorithm which estimates the rise and fall times independently. They found the '''average time from explosion to B-band peak brightness is 17.38 +/- 0.17 days'''. This average rise time is shorter than the 19.5 days found in previous studies.
