I've updated my every block timed project to be (much) more accurate and include literally every single block. You can't run the tests without a special timing block mod which isn't available yet to the public so for now just enjoy the improved RTC table. RTC = Relative Time Cost. This is each block's time cost relative to the cost of the minus operation. E.g Move has an RTC of 7.1 meaning it takes 7.1x longer than the subtraction operation. (Uncertainty is ±15% for math operations and ±20% for other operations) *Note*: if the block has a wait component its RTC is determined by the wait. Certain blocks depend on list/string length, costume size, pen size, pen line length, gpu specs. **If a block has an RTC of exactly 5000, it means it causes a screen refresh and i've given it an arbitrarily large RTC value. Commands (won't work without the mod): t: test all m: test motion l: test looks c: test control s: test sensing o: test operations v: test variables p: test pen 0: test other (sound, custom blocks, broadcasts) 15/10/24: Have replaced O(n) operations with their linear RTC equations, where n is the length of the list/string that the operation is applied to.
