I'm not so sure about that. Again I would normally understand that 10 is included. The nuance has changed by using "up to" suggesting that this is not just a series or set but a limiting statement with 10 as the upper limit and emphasising that there is nothing beyond. Again, if there was doubt, I would add "up to and including 10". Sorry but English isn't always very precise.Thank you!
How about 1 up to 10? I think 10 is not included here, am I right?
