We've increased the deadline for SR5 tasks to 6 days. With larger numbers come longer processing times. Since it also takes up to 4 times the normal time to process a number when a prime is found, we feel this increase in the deadline is warranted.
Since there's still several hundred SR5 workunits in the pipeline, you may still get some SR5 tasks with 3 day deadlines, but all new workunits will have a 6 day deadline.
Note: Some older CPUs such as an AMD Sempron may run SR5 tasks up to four times slower than they run other LLR tasks. Therefore, if you have a really old computer (like my 32-bit Sempron) and are lucky enough to find a Riesel prime, you won't be able to complete the processing within the deadline. If your computer can't complete an SR5 task in 36 hours (1/4th of the deadline), it won't be able to make the deadline if it finds a Riesel (-1) prime. Sierpinski (+1) primes "only" take twice as long.
When deciding whether to process SR5, please keep this extra processing time for primes in mind. If you have a very slow processor and miss the deadline, you may miss out on getting credit for discovering the prime or being the double checker.
