Yep, 2x daily dosing is optimal for pretty much atleast every oral. Dbol is the one that I rec. doing 3x daily, or any oral that isn't a DHT based one, so Methyltest would be another.
50mg of Anavar if it is legit will produce noticeable gains, 10-20mg+ alone is good for collagen synthesis itself but in terms of results you may be a little let down. Me personally, I would go with 100mg of Anavar based on most people saying it's effects shine at that point onwards, but cost is usually the deciding factor (as it for me, I can't justifity Anavars price when I can get more for the same with Winny).
