What the multiple means for allotment
Retail bids ran to about 28.93 times the shares earmarked for the category. When a retail book is oversubscribed, the registrar does not allot proportionately — allotment runs as a computerised lottery among all valid applications, with each successful application receiving at least one lot of 1600 shares — ₹1,20,000 of stock at the upper band. The multiple above is the data point that determines how thinly that draw is spread; it describes the final book, not the outcome of any single application.
