Nice mate. Normal take off for A320 should around 140-150 kts. 170 kts might similar with MD-11. When stall, push plane down to gain speed & climb again.
Well the speed V1 and rotate is depends on the FOB weight for example (fuel 19,900 KG meal 150 luggage loading 250KG) it was too heavy to takeoff the v1 calls off then around 7 seconds the rotate calls out so I checked the speed it was 165 kts after the rotate calls out . (honestly I was an A320 student pilot “not well trained” if there’s anything wrong with this reply please suggest an edit)
