Re:
I lift my foot off when am about to change gears manually, but I think it doesn't make a difference. Anyway, I have used it for prolonged period of time as it just felt a bit weird

Re: Re:
quote: Are you meant to keep your foot on the accelerator when you go up/down the gears?
In Manual mode, personally, I keep accelerating with the foot down when down-changing during a hill climb and when up-changing for maximum take-off at the lights.
The foot is naturally off the accelerator when dropping down a gear to use engine braking on a downhill run.
There is no clutch interface so when you do select a gear with the + (push stick forward to go up) and - (pull stick back to go down) gear selector, it allows the gearbox to select that particular ratio.
As I understand it, all the manual select does, is to tell the continuously variable gearbox position/ratios cones to use the only the positions which correspond with the normal Manual (or Auto) gearbox ratios.
Being Semi-Auto in that mode, you don't need a clutch and if the gear ratio you select is too high for the load, it will still decide to operate in a gear it regards as more appropriate for the load on the engine/gearbox (up to, but not exceeding , that which you chose).
e.g.: You might select 5th on a steep hill at 2000 rpm, but that only tells the manually over-ridden CVT that you are willing to go up to 5th.
The gearbox 'brain' may disagree.
The gearbox brain then decides which gear is the highest it is prepared to accept and use without damage... it might prefer 4th (or even 3rd) when you choose 5th , so it will only change up to your selected gear when the transmission load is low enough to allow 5th comfortably within its preferred rpm and load range.
Note: I would hope that anyone using the manual over-ride was actually skilled enough to improve on the CVT default selection by driving it as if it was a real Manual and selecting the rpm and load to get the best from the combination.
Bottom line: it is safe to experiment with the joys of Manual over-ride as that gearbox does protect itself from short-shifters.
However, it does allow over-revving at relatively low speed in a wrongly selected low gear as it won't change up beyond the highest gear available in its manually constrained selection. Do that at your own peril.
