I want to know the answer to the following question:
How much slower do games run on PAL consoles than NTSC due to frequency differences?
All the background I'm provided with is that "PAL consoles face another incompatibility when playing out-of-region cartridges: the NTSC video standard specifies video at 60 Hz while PAL operates at 50 Hz, resulting in approximately 16.7% slower gameplay.". Is that enough to answer the question?
Answer: yes
