Thank you sushdmehta and mulderpf for your thoughtful input.
While I am still looking for more inputs especially some personal experience of anybody, but based on the discussion and your valuable input, here is how I have made up my mind.
The most ideal thing would have been applying within 2-3 days as things are getting tougher due to cap/limit on number of visas and the fact that the November 2010 quota has already filled and all new applications will be queued for December. This way every passing day make things harder.
But still applying and applying with correct documents is important.
----------------
If I apply within a few days as 3 months maintenance requirement of 2800 gbp met yesterday with a single day dip and raise in between as discussed in the topic,
There is a risk of
1. Refusal without right of appeal
2. Refusal with right of appeal
and in ideal state
3. Chance of Success
With 1,
Money and time is going to waste. The importance of time has increased manifold due to the cap/limit as refusal would mean a fresh apply would be required, hence putting oneself to the end of a lengthy queue with no time limit known.
With 2,
If appeal is granted then good otherwise time is going to waste and even worse if appeal is denied again as that will push me even farther in the queue with a fresh apply.
-------------------
Another way out is to wait for a month (till mid December) as in my case I can apply after a month with a perfect maintenance fund scenario having the slight transactional dip in balance washed away. And if the conversion rate gets better may be I am able to apply before a month.
In that case, although I will be late at most for a month and my application will be queued with the results of application getting late but it is still a better scenario than 1 and 2 (discussed above) as the risk factor will be eliminated and the chances of success will be brighter.
-------------------
I think waiting for the best time to apply with a risk free application and ignoring the visa cap constraints is the right way to go??? unless a clear proof of some real experience supporting the closing day balance scenario is shared here sometime soon?
Please advise.
Thanks for the patience and support
