I agree somewhat, but the length of the run makes a difference in what is required also, plus if you plan to run other loads from the outlets like air compressor and oven both. You would need to run wire heavy enough for both loads and a breaker big enough for both loads, but wire to each load could be much smaller than from breaker box to outlets.

If 25' from breaker box to outlet near oven you may need a heavier wire than just 5' from outlet to oven.
In any case the wire from outlet to oven must support the full load of the oven running at full blast!
If you have figured correct and 14AWG supports the load then go with 12AWG at least.
I always oversize the wire at least one size and under size the breaker for the wire. If a problem happens a 50amp breaker will trip before a 100amp wire burns! A short in a 30-40amp device should still trip a 50amp breaker.
